In most countries, certainly the UK where I live social security payments in are made from workers to the government. At the same time the government pays out social security to those in need. There is no fund, payment in approximately matches payment out. It is not a ponzi scheme, it's normal government taxing those with money and paying out to those in need. It's nice the US has a fund but it's not necessary.

I get the "joke"

My point is that its not a scheme and no damn politician is going to take social security away from us. And I and most others disagree with changing it to not be universal
