The boomer generation starts to retire and F.D.R.’s Ponzi scheme finally collapses,but wait if we legalize 20 million illegals with amnesty then we can keep the scam going! Sadly what these dual “citizens” will do is work off the books or send the money home under the radar so that the anticipated revenue will be nothing but an illusion.
The vast majority of Mexicans and South Americans who immigrate here illegally will never, ever play "European Welfare State" even if made legal. Never. Exactly as you say they'll go black market within their own communities and like southern Europe we'll have a good 25% or higher chunk of the economy that is black market.
It'll collapse in short order. Ofcourse, that may be the plan.
An amnesty will make the SS situation worse. Even illegals grow old and they will get more out of the system than they are contributing. 53% of all immigrants in this country are on welfare. We are importing poverty through our legal immigration policies, which bring in 1.2 million immigrants annually.
