I just want to make friends!
I think a better solution would be to tax all income but have a maximum monthly payout. And maybe not tax all of it at the same rate. For example Social Security tax is levied on the first $100k or so, maybe add a 3% tax to all income above that without an employer match. Or more, or require the employer matches too.
If I'm making over the current limit and get hit with that new 6% tax, I'd better be getting a proper increase in benefits to go along with it. Otherwise, if it's practical, I'm going to opt for better benefits in lieu of the money that would be taxed.
