SS was fixed for 50 years in the Reagan era
Reagan and Tip O'Neil set it up on a path where it generated a surplus for many decades. It's an easy fix now too.
The current maximum amount of taxable earnings for Social Security is $176,100. So anyone making more than that pays the exact same amount in as someone making $176,100. Elon Musk, Jeff Bezos, the orange shitatain, etc all pay SS taxes only up to the first $176.1k they make.
As Bernie Sanders says so often, raise the maximum amount of taxable earnings for Social Security to $1 million, problem solved for 100 years.
