Oh, I think I see what happened. My attempt at sarcasm, (my comment about the Interstate Highway System), failed spectacularly. I thought you'd catch that but you took it seriously. I'll own that one.
I don't think there should be an option to opt out of SS. Instead, I think the contribution limit should be abolished.
You could monkey with the contribution percentage but I don't think it should drop to zero at $137,700 for 2020 and $142,800 for 2021. If the fund is failing, stop capping the individual contribution at less than $9000 (plus the same from the employer). Someone who earns $145,000 contributes the same as someone who earns millions, which doesn't seem fair to me.
I also don't think employers should contribute an equal amount as the employee. The employer should just pay the employee and have it deducted on that side of the ledger. Same with health insurance. I've always been opposed to employer-provided health care, a position I've held since the
1970's, but that position has really been strengthened this year with millions of people losing their jobs and simultaneously losing their health coverage. As a country, we need to remove employers from the health care and Social Security picture..
