I would just like to remind everyone

that any country whose native population fertility rates are below replacement level is a failed state.
That includes USA, all European countries, Japan and South Korea.

why would you want overpopulation?
there will not be enough resources...

States with fertility rates equal to replacement level are not overpopulating and do not require immigration to support their economies. However, US, Japan and Europe have much lower fertility rates than would be required for their survival. These failed states are literally going extinct and being overrun by foreign immigrants (except Japan which is just going extinct and overaged with no immigrants).

So then only those states with fertility rates exactly equal to replacement level are not failed states. Which states are those?
