In western countries, whites have stopped breeding while non-whites keep breeding.
Japan stopped breeding in the mid 90s when Soros cratered their economy. They don't allow mass immigration like the west does.
Strangely, muslims have no problem being only welfare while hveing several wives, when their religion says they can't have more than they can personally afford.
The UK allows muslims to have 5 wives, as long as they only married 1 in the UK. Polygamy is illegal for everyone else in the UK.
