You aren’t sure what period is being looked at...over the next two decades, 10,000 baby boomers will retire each day. Maybe you can understand how paying an additional 80 million people can lead to an unfunded liability of $13 trillion, which is a figure comes from the Social Security Trustees. Your retort is the stuff of liberal propaganda...without having people depend on the government to provide for their retirement is going to led to millions of people dying in the streets...spare me the melodrama. Why does the Federal Government need to take my money...turn around and give my money away to others....all on the promise that if I live to age 65...they’ll take someone else’s money and give it to me...but wait...they currently are paying out more in benefits than they are collecting...you could retire with more money by simply opening up a savings account...but people like you still endorse this idea that we need the Nanny State.
The trillions of unfunded liabilities in Figure II are calculated over some number of future years, but I haven't spotted where that information is given, if it is in the discussion. It be good to know how many years out they calculated. It might go out until all those currently in the system reach retirement age. - All your rambling does not answer that.
Like many on the left and right, you live in your own little fantasy world. Gripe all you care to, but nothing will change the fact that some form is safety net is needed for those of working age, and some form of assured retirement income is needed for the retirement age citizens. And a fair number who thought they were just as savvy as you think you are saw their comfortable retirement nest eggs cut in half or worse during 2007 - 2009. Like it or not, there needs to be some amount of assured retirement income. Otherwise, we'd have varying degrees of anarchy and all sorts of social ills few Americans would care to have as part of the daily scenery.
Your ideal society where everyone provides for their own retirement voluntarily will come about at the same time as peace and love exists among all mankind and the lion will lie down with the lamb.
