I’ll read that article later, but that doesn’t sound right — there can’t be so many multi-millionaires that them getting free money is stressing out the system.

Quick random googling, I’m seeing the number 3.2% of retirees have more than $1m

And I can’t imagine social security would become suddenly profitable by a <3% population delta

Furthermore, multi-millionares have at least 2 million so they are significantly less than 3%.
