Because the US is run by wealthy people and highly corrupt. If it isn't a problem for those with money, nothing will change. Look at all the major problems the US has and nearly every one of them can be easily walked around if you have a lot of money. Expensive healthcare? Well I got money. Overzealous police force? Well in an expensive neighborhood cops don't dare harass/extort random citizens. Harsh and exploitive justice system? Money will bleed to courts dry until they give up. Shitty local schools? Private education. Shitty infrastructure? Buy large SUV and generator. Polluted water? You can get good water delivered or run a whole-house reverse osmosis system.

It is highly inefficient, but if you are on top of the wealth pyramid none of that matters to you. Average citizens however can't afford all of that.
