So many things wrong with this statement.
For one the closest habitable planets are light years away, and we are thousands of years from developing light speed or FTL travel. Secondly, even if we had the technology, fuel is another issue, and thirdly even if all the aforementioned were possible, do you really think the wealth gap would have resolved itself? At best the very rich and then the valuable members of society would be taken and the rest of us would be left here to die. Nah humanity is dead, we could reverse the damages, but no one cares enough for that to happen.
