besides [illegal] votes, this is also about economics
they need immigrants, legal or not, as revenue streams to maintain their exorbitant social programs. democrats will bleed the wealthy [or borrow trillion$ in YOUR name] to fund the programs until later generations are integrated and no longer in need of hand outs. conveniently, bleeding the wealthy brings them down a few notches and a 'more equal society' is established.
democrats know social security is going to collapse under its own weight without more people paying into it - the same as it is for europe. once that collapses, so will the others and proves their system was a sham in the first place despite saying the others just werent doing it right, unlike them. they will never admit this and will bet your future on it.
would you give them another chance with your money?
