Hate to say it, but until Islam gets reformed, allows woman to educate themselves, allows the removal of burka and hijab, and stops allowing their 6 year old daighters to be married, and learns how to work outside of the government jobs. They will never assimilate, and only bring the culture they are invading down. This has happened to so many countries. Then once one of them gets into power, they change the system, try to implement sharia policies, and eventually turn it into thr same place they left. It happens over and over again with Islam. people's niceness will be taken advantage of.
BTW, I don't buy the "not enough people to work" theory. They said the same thing about slavery. And then walla new technology was invented. Just like what AI will do.
