One more thing, you were talking about European immigration into a dominant European culture. Third World Latin American and Asian immigration into a first world European culture is not the same.
I didn't want a large passle of children and neither did / do many others. Money, though sometimes a consideration, had nothing at all to do with my decission . Neither had it / has it on other peoples' views of how large / small a family they want to / do have. Only someone living an isolated life, could make the kinds of statements, that you continually make. There is no, zero, zilch proof that people would have more kids, IF only taxes were lower. OTOH, there is a massive amount of proof, that the more educated and wealthier people become, the fewer children they have. These studies, FYI, have been done for about 100 years.
I see that you're back on Latin and South American, as well as Asian immigration. You have stated that you want ALL immigration should be stopped. That includes Caucazoids ( whites, to you ) and some Latin & South Americans ARE not only white, but what you would think of as " EUROPEAN " , as well. Now, what about the white farmers in Zimbabwe, or the Afrikaners in South Africa or the Irish ( BTW, ILLEGAL Irish immigrants have flooded the USA !), or Germans, or others, who would meet your racial criteria ?
