The fact that saying $4k net per month on the side is "not good" and "does it to survive" is showing what a failed and depraved country the US is.

There is 60 countries in the world, where the annual GDP per capita is lower than that, and only 20 countries in the world, where the GDP per capita is higher, if we multiply the $4k by 12.

If we assume this to be taxed, then only the tax havens are above that and that is certainly not going to reach most of the people living in these tax havens.
