If we cut immigration to say 200,000 per year allowed, send home all the illegals, this country would be close to the 250 million people instead of 300+ Million. Why do we want to be crowded? Who does this benefit? We all know, the businesses that want cheap labor, and the cities who want to cram everyone into small apartments so they don’t lose a single cent of the tax revenues that used to be paid to NO ONE, because in the Counties, much happens without money changing hands.
Not that you have a bad idea but we’d still be crowded.
There is plenty of habitable land today for people to live on uncrowded even at this population level. Most of us choose to live on top of each other in cities, leaving the rest of the country uncrowded.
Thankfully.
