Deduct all welfare they have gotten from the time they were born - medicaid, food stamps, SNAP, WIC, free school uniforms, all school fees and school supplies, Section 8 housing, free college, free transportation, free hospitalization and then see how much they owe America back.
Ungrateful.
Add in the violence, looting, and rioting that has damaged America...I think Americans are owed a lot.
Oh, and add on nonpayment of state and federal taxes as well as college programs that give them stipends for being in college. I spoke to an AA man who laughed as he talked about his 3 COLLEGE degrees and how he got paid to stay in school and not have to work. All expenses paid - food, housing, transportation and all college/books/computer/fees PAID FOR COMPLIMENTS OF YOU AND ME.
