To them, there is no America after they die. A religious person would conclude that if they don't even conceive of a better country after they die, then they probably don't even actually believe in God.
They are willing to throw away the one last chance for a sane planet in lieu of a bunch and third/fourth/fifth world immigrants who will vote to keep them in office during their lifetimes. After that what do they care if the US becomes another Zimbabwe, Venezuela or Guatemala?
U.S. citizens don’t need to create kids anymore, look at all the ones odumbo is bringing here as ready made democrats.
When these currently illegal but future “American” kids grow up and realize what a great place this county is (or was before they got here) and they get all that free stuff (until it runs out), they will support their “king” forever.
