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.
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
Social security is already being cut. Elon is slashing their budget, removing offices while requiring more visits for services. They're starving the beast so they can claim it doesn't work, which means they'll have cause to eliminate or destroy it. Social Security is about to bottle neck to the point they can't fulfill their mandate. This is by design.
It doesn't matter what you or most others think. The US Govt is being held hostage by like 4 people right now and they don't care what you want.
