While the world as a whole is still struggling with population growth and climate change, some countries, like Russia, are worried about their population declining. Who wants to live there? Meanwhile, here in USA, we seem to have more than enough people wanting to immigrate here.
I got to thinking, if there was ever a worldwide shortage of people, democracies that respect human rights would be at an advantage. There always seems to be enough, if not more than enough, people wanting to move to USA, Canada, Australia and some western European countries.
If there was ever a worldwide shortage of people, countries would have to compete to attract folks who want to live there. It might encourage countries to become more democratic.
There's the phrase, "vote with your feet."
Ironically, countries that respect LGBTQ rights (the rights of people less apt to reproduce) might see their populations increase as folks flee the more bigoted countries. The more democratic countries could be bouyed by growth of their internal markets, workforces and talent as those are the countries people want to move to.
Remember, Einsien was an immigrant.
USA seems to have no problem attracting people, but it is trying to limit immigration. Growth does bring growing pains. While we seem to respect human rights more than a lot of other countries, we have our problems accomidating growth. Rising housing costs, water shortages, nimby neighbors, traffic. One problem is, we are still too dependent on the space gobbling automobile. Acres of free parking may have to go.
