They... they are still pooling wealth. Their wealth will simply be from other things than another country.
The US has oil they could pool wealth from. They have resources they could pool wealth from. Things they could invest in. But. They. Don't. They aren't even adequately taxing the folks that can withstand the tax the most: The wealthy. They used to, but it isn't like that now.
There are little things the US simply doesn't do either - just in healthcare. For example, the Norwegian system will send a home health nurse to you up to 6 times a day for short visits. This is because it is cheaper to do this than to house you in a nursing home, overall. Even if you are living on an island. The US expects you to have family take care of you: Poor people won't get home health visits, in no small part because when you don't pool your money together, things like home health care aren't affordable.
(sidenote: The home health visits aren't always adequate, but better than nothing).
Pooling money to increase everyone's wellbeing doesn't take winning a lottery.
