What...

Raises so many questions. Does he want it for the U.S. or mostly for himself? While the former is assumed, it never really says either way. Already wants to act picky about
legal immigrants, but, hey, lets just basically buy 55k people.

Would there be an individual vetting process and he'd deport them off the island if they don't measure up? And has he considered that we already have plenty of states that collectively require a lot of tax dollars to deal with winter, without needing to add an island that for a good chunk of the year is basically
made of winter?
The reactions of the citizens though... “Oh please God no”...
