there wont be any integration, you need one imigrant surounded by 9 hosts to force him to assimilate-to survive. If you import millions of them they simply recreate their country in your host country while parasiting it and killing it from inside, willingly. Those who modified the laws to import them dont care, they dont deal with them they live at the top of the pyramid. But it's beneficial to them to lower salaries of the sheeps they give jobs to, owning the capital , machines, plants.
White people stopped reproducing, they ll get replaced, as simple as that.
Immigrants dont respect the values of a dying, self hating hosting population, they replace them and enjoy every secnond of it.
