A key problem with the economics of Social Security is that the Baby Boomer generation is so large that we need a larger group of working age people to compensate for that temporary population bubble. The irony, of course, is that the two ways to make up for that are to increase the taxes on the wealthy and to allow for more immigration so we have more working age people. By shutting off the immigration spigot Republicans are making the higher taxes more necessary.
Reminds me of their policy to shut off funding for family planning which in turn creates the need for more abortions.
Do they even think these things through for 5 minutes?
