They don't want to live with the illegals, they want us to live with them.
The progressive wet dream is government, or corporations in bed with the government owning housing that is dense and urban. They get to choose your neighbors, and what kind of house you live in. No more escaping to the countryside or the burbs to get away from crime, graffiti, litter, and noise. They plan to bring all of that to the burbs to make all of us equally share in the misery.
There won't be any small business or self-employment. Everyone will work for the man. If you upset the corporate overseers, you'll lose your house, your kids will be taken away from you, and you will be destroyed.
The monetary system will be completely digital, giving them complete control over how you spend your money. No one will own cars. Everything will be public transit, and they will control where and when you can travel using that digital monetary system. Healthcare will be provided by the government, and the progressives will decide what healthcare you get, and how much.
No guns, no weapons, and only white males will be prosecuted for crimes to allow minority groups to take over. Self defense will be illegal. Tech will eliminate privacy, and everything will be watched by big brother.
They will control what you eat, what you read, watch or listen to, and everything else connected to your existence on this planet.
You may think I'm crazy, but I've read history, and I watch what's going on in the US today. I see striking similarities to what happened in Russia, China, Cuba, Venezuela, Cambodia, and the rest when communists took over those countries. And most Americans seem to be oblvious.
