My Dad Is Leaving My Sister Twice My Inheritance — He Says It’s Because I Handle Money Better

A father thought he was doing something simple: meeting each of his kids where they are, financially. One son saves and wants to learn about investing. His daughter started working and surprised everyone with how quickly she built a balance. The middle child? He works the same job, but spends nearly everything. Now the parents are fighting over whether the differences in support are fair—or quietly turning into a permanent family label.

The dad laid out the details in the original post, framing it as a dispute with his wife. He says he isn’t trying to punish anyone. But the way money and perks are flowing in the house has made Kid 2 feel left out, and his wife thinks the family needs to “correct” that before it hardens into resentment.

Three kids, same job, wildly different outcomes

The father has three children: a 19-year-old son, a 17-year-old son, and a 14-year-old daughter. He says they’ve all held the exact same summer job, with the oldest now old enough to work as an adult during the school year. On paper, it sounds like an even playing field.

But once the paychecks hit, the differences show up fast. Kid 1, 19, saves money and has been actively learning about investing with his dad. Kid 3, 14, only started working this year but already has “7 times more money” than Kid 2, which the father calls a pleasant surprise. Kid 2, 17, “saves no money,” spends on friends, and doesn’t show much interest in saving or investing despite getting the same guidance.

That last part matters because the dad insists this isn’t about favoritism—it’s about behavior. In his view, every kid got the same talks and the same offer of help. What differs is what they do with it.

Where “financial education” turns into real perks

The conflict isn’t abstract. It’s not just a lecture about budgeting at the dinner table. The dad has made concrete financial moves with the kids who save, and those moves look like advantages.

With Kid 1, he sold his son a car for $5,000 in cash, even though the car was worth around $9,000. The dad says he first tried to give him an old stick shift, but the son wanted a bigger car, so the family sold him another vehicle instead.

Then the car broke down within six months. The father says he tried to make it right by buying the car back, and the two agreed to use it toward a down payment on a Toyota RAV4. The father now covers half the payment, while Kid 1 pays insurance and the other 50% of the loan payment.

With Kid 3, the daughter, the dad says they’re looking at setting up a child’s investment account. He also describes what he calls the “Bank of Daddy,” explaining that her bank account doesn’t offer certain investment options like CDs, so he’s borrowed money from her and is paying it back with interest.

To the dad, these are tools: a way to reward responsibility and build momentum. To his wife—and likely to Kid 2—those tools look like a pipeline of extra support that only flows in one direction.

Kid 2’s spending isn’t subtle, and it’s hard to watch

The dad doesn’t portray Kid 2 as a bad kid, but he does describe spending habits that would make any parent wince. He says Kid 2 has “next to no money,” even though he’s doing the same work as his siblings. The dad compares him to Kid 1 at the same age, saying Kid 1 had nearly $10,000 by then.

What’s driving the gap, in his telling, is social spending. Kid 2 likes to hang out with friends and “throw money around.” The dad adds that it isn’t a huge red flag at 17, but it limits what he can do to help him in the same way.

The most concrete example he gives is the kind of purchase that feels small until you add it up: “ordering $60 worth of Wendy’s for 2 people through Door Dash.” The dad says Kid 2 gets upset that he doesn’t have money, but also gets upset when the dad tries to explain why choices like that are a problem.

That’s the trap the father says he’s stuck in. If he helps too much, he thinks he’s teaching Kid 2 that someone will always patch the hole. If he doesn’t help, Kid 2 feels excluded while watching siblings get cars, interest payments, and investment accounts.

The marriage fight: equal treatment vs. equal opportunity

The wife has been watching these separate arrangements develop and believes something needs to change so Kid 2 feels “more included.” The father pushes back hard on that framing. He believes he’s doing “the exact same thing” with all three kids: offering guidance, education, and help—then letting their choices determine the results.

But even in the dad’s own description, the outcomes aren’t just different; they’re visibly different. One kid is splitting payments on a newer vehicle after getting a heavily discounted car purchase. Another is being set up for early investing and effectively earning interest through a parent-run setup. Meanwhile, Kid 2 is being told the lesson is discipline, and discipline means no bailout.

The father acknowledges he could do things to “make him happy,” but he views that as short-term comfort that undermines the long-term goal. His central point is that discipline can’t be taught if bad decisions are quietly covered.

He also adds an edit clarifying one detail that bothered some readers: he says he did not “need” to borrow money from his daughter and insists he was acting as a bank to give her access to a form of return she can’t get through her account.

What readers zeroed in on: optics, fairness, and the “Bank of Daddy”

Even without a blow-by-blow comment section included, the father’s edits make it clear what people latched onto. Some questioned the idea of borrowing from a 14-year-old at all, even if interest is paid, which is why he emphasized it wasn’t out of necessity and was intended as a structured lesson.

Others focused on the unequal visibility of the benefits. Financial education is one thing, but a discounted car sale and shared loan payments are the kind of support kids remember for decades. If Kid 2 is already sensitive about money, watching a sibling get a deal worth thousands could feel like a judgment, even if the dad sees it as earned.

The dad also pushed back against commenters making assumptions about deeper issues. He says the post wasn’t meant to imply contempt for Kid 2, denies that Kid 2 has ADHD, and says they share plenty of interests and time together. In other words, he’s trying to keep the story narrow: this is about money habits and parenting strategy, not a broken relationship.

A family lesson that could outlast the teenage years

The immediate question is whether the dad should change course to avoid leaving one kid behind emotionally. But the longer-term stakes are heavier: once parents start setting “systems” with their kids—cars, loans, investments, interest, and special deals—those systems can start to look like a family scoreboard.

The father wants Kid 2 to learn the discipline that saving requires. The mother wants Kid 2 to feel included enough to stay engaged rather than checking out. And Kid 2, stuck between lectures and temptation, is watching what happens when responsibility pays—and what happens when it doesn’t.

The uncomfortable part is that everyone may be right in a different way. The dad’s approach teaches consequences. The wife’s worry is about the relationship consequences. And unless the parents agree on what “fair” looks like in practice, the money lesson may end up becoming a lasting story the kids tell about who was trusted, who was rescued, and who was left to figure it out alone.
