Is it ethical to forbid and add limitations to the families to have only one/two children? And if they exceed the limit, thy would have to pay taxes. (like in China). Is it great job to create a factory, which literally produces babies like a breeding machine and get paid, because government pays you some cash for increasing the youth in the population? (like in Denmark).
Is it ethical to make more children just to indulge and develop your bloodline, your roots, while millions in another part of the earth are dying from starvation…
