NIMBY so we aren't making endless homes. This is because people WANT their home to have value and be a scarce resource that makes it possible to get rich through your home. Its literally the only way to move up in the world. Its actually a feature not a bug of America.
Please note that China tried mass producing homes and then it gutted their middle class and poor, crashing their value. Took at least a decade to repair it.
All you can do is try to save money and eventually you will buy a house, just like the marriage meta went into mid thirties, you probably get your first home in your late 30s early 40s. You still get one and then you will make big money.
Eventually everyone will get a house through inheritance or buying one.
