The population has grown such that urban areas have far less acreage per person than they use to, so there's more competition for housing in that neighborhood.

Plus, income distributes follow a pareto distribution: in DC a 60th percentile family earns between ~35% more money than an 50th percentile family does, and a 70th percentile family earns ~35% more than a 60th family does, etc.

Those two factors are behind the explosion in housing prices around the nation. The same number of people can afford to pay substantially more for housing than they could previously. When you were growing up, your parents were competing with median income families for housing. But today, you're competing with ~70th percentile families for the same housing (per your income assessment).

The solution is to tear down low-density suburbs and replace them with high density residencies. But there's no incentive to do this because people are more than willing to just spend more time commuting so they can have a yard to mow on the weekends.

It’s hard to tell what people actually want. The lots in my neighborhood, laid out in the 1930s, has a standard plot size of 1/15 of an acre. This is a suburb of detached single family homes. A few people have doubled up the lots, but for the most part people just deal with having no yard. Today, the minimum lot size is five times bigger, 1/3 of an acre! So is there no incentive to build denser because people are willing to commute more to have the space, or because it’s illegal to do anything other than build ultra low density housing?
