You almost got it right - it's about stealing money from other people's kids and grandkids. Oh yeah, your children and grandchildren are working for me now. If you don't support the ponzi scheme, you are, frankly, Un-American (it was set up by all-American politicians, you know).
Hey legal & illegal immigrants - jokes on YOU! The school system sucks and you'll be taxed-to-death to pay for my retirement entitlements. Hahahahah.
They have the last laugh --- you're paying for those kids they're having --- their post-natal bills and school --- all money that you could have for your retirement has to go to give them their free school, college, and health care. Also don't laugh but many of the immigrants coming in now are elderly, coming here for a cushy retirement themselves that they never contributed to.
