Salmo,

They go to work and endure payroll taxes like the rest of us who work. The Gov then takes some of that money and pays your pension and social security.

Bonus. Illegals pay in but don't take out.

Thus the pyramid scheme survives a wee little bit longer. We need them to prop up the top half of the pyramid.

Works great as long as there is job and wage growth but as you noted in your future thread that paradigm ain't gonna last much longer.
