Humans will never get off earth and populate other planets

Humans can't prioritize their infighting and public spending to undertake such an effort.

We are fighting over gaza, the mexico border, drug cartels and other petty things an advanced civilization would solve in a day. we will always fight over them because these issues make our leaders money.

There will not be any funds left to spend Trillions? just to put a signficant population on Mars.

Wars among each other will prevent us from populating other worlds before our own is wiped out in a nuclear war or asteroid.
