Very straightforward -- if you gave people the choice between paying taxes for some payback at a future date, and just having the money now, then people will just take it now. Will they invest it wisely for the future? Nope. They'll spend it on putting spinnas on their crap-mobile, or on booze, or be off to Vegas. So it has to be mandatory.
silmdave, could you explain that a little more? How could greed possibly make contributions mandatory when most know something is amiss with the whole social security system. I can understand how stupidity could play a part, but greed?
Well, that's no more true than the "imagine a mushroom cloud over New York" argument was for invading Iraq. It's pretty much an outright lie.
"As a matter of fact, by the time today's workers who are in their mid-20s begin to retire, the system will be bankrupt. So if you're 20 years old, in your mid-20s, and you're beginning to work, I want you to think about a Social Security system that will be flat bust, bankrupt, unless the United States Congress has got the willingness to act now. And that's what we're here to talk about, a system that will be bankrupt."
