We as a society can’t even agree to guarantee basic fundamentals needed to live in the US. Flint, MI still has tainted water, millions are unemployed, homelessness is rising and some are starving.

We can’t take care of our people on this planet, what makes you think everyone, or even most people, would be the ones chosen to be on the ships headed for a new life? Just look at what billionaires spend on private doomsday shelters, you think they’re willing to accommodate the masses? Migration from Earth under those circumstances would look a whole lot like the Titanic tragedy: life boats for the rich and powerful and certain death for everyone else.
