Sounds like it’s just you and a brother, a few generations ago 5-10 kids was normal, and a house didn’t mean much because it’s value wasn’t inflated.
Common people are actually able to inherit significant stuff now, which considering government inaction, is pretty much the only way to rebuild the American middle class.
It’s slow, and it sucks, but over time it leads to improvement.
Like say two families have two kids, and only one kid from each goes on to have kids, for simplicity we’ll say with each other. The grandkids are going to inherit from their grandparents, parents, and childless aunts/uncles eventually. That’s three houses, even if there’s nothing else
That’s wealth concentration, it’s how the upper class has been doing it for centuries.
