I'm one of the older of the Baby Boomers. Fortunately, I should be able to stay out of the wagon. I know many SS/Medicare recipients who don't really need the help, but they take it anyway. Obviously, as this crisis worsens, many of them will be forced out of the wagon. However, there are also many, many seniors who will never be self-sufficient.
Your charts illustrate the problem. But, as indicated, I like to look beyond the crisis. Right now, we have a large and growing number of benefit-hungry Baby Boomer seniors who are going to be a real burden for awhile. After we're gone, though, this country is going to have a real opportunity to get back to having a small government.
We have an aging population period. If you look at the graph for 2060, you will notice another huge bulge around the 35 to 45 year olds. As this cohort moves thru the system, we will have similar problems to those associated with the Baby Boomers. People are living longer and this has an impact on the entitlement programs and the size of government, which essentially spends most of its time redistributing wealth.
I don't share your optimism.
