Exactly!
A lot of American college kids cannot get credit for quarters they work during college off-campus because they don't make enough each quarter to qualify but they still pay into the system and it is not returned. Now they want to have illegals only work 18 months and qualify? That is an insult IMO.
That's why I told my kids to work for the University because they never take out for social security. None of the kids have been on work study either. It has been great that they didn't lose a dime to social security when they couldn't get credit for it anyway.
