Was wondering if there are any tax strategies that high income earners -whose earnings come primarily through w2 income- can use? Aside from starting one's own business, using a backdoor Roth conversion/contribution, and trying to generate more dividend income, are there any strategies you can reccommend?

Ummmm....assuming your W-2 income isn't affected by your dividend income (I know mine isn't), generating more income in taxable accounts via dividends will increase your tax liability, not decrease it.

One other possible solution - quit your job. ;-)
