The plan is to fill the big cities with immigrants, causing them to collapse, which will push the liberal Americans now living there out into the red states/counties, to make them purple.
Yup. NYC for example still has a lot of buildings going up. Many of those buildings are hotels in the outer boroughs.
Who the heck would travel to NYC and stay in a hotel in the outer boroughs?
As you say, they will be future homes for immigrants, built with our inflated dollars, BTW.
