Is this wrong?
"If you file taxes as a single person, your Modified Adjusted Gross Income (MAGI) must be under $139,000 for the tax year 2020 and under $140,000 for the tax year 2021 to contribute to a Roth IRA, and if you're married and file jointly, your MAGI must be under $206,000 for the tax year 2020 and 208,000 for the tax year ..."
You can do a traditional IRA if you exceed those numbers, but can't make it tax deductable. So, you have to invest with after tax $, it does grow ta deferred, true, which is good for dividend reinvestment and if you move stuff around a lot, but then you pay taxes again when you withdraw. So a 401K (if you have access) is better as you can at least deduct your contributions, but your investment options are more limited (although you ought to be able to get a low fee S&P 500 index fund in any 401k)
