Multiculturalism has been an absolute failure. Integration in schools has destroyed the public education system. Integration of neighborhoods has brought crime and violence to the suburbs.
The whole purpose of government social engineering has been to put the middle class under the control of the political class.
It was the left that invented segregation, remember. And here they are pushing it again. So the opposite is not necessarily a failure, especially when the left-dominated “communities” push the destruction of the family and everything against Judeo-Christian morality. Don’t fall into the left’s trap.
As for “the public education system”, the fact that it’s government-controlled ought to say it all, never mind their persistent opposition to homeschooling.
