Almost nobody puts up $1,000,000 on a W-2. That's why pretending that billionaire income taxes are too high. Because they do not pay income on the vast majority of their income.
Most folks that could knock down a $1,000,000 W-2 are business owners, and way too smart to pay taxes like "the little people." The business owner would simply convert the ordinary income into dividend distributions. And turn that regular income into cap gain. Then instead of paying that pesky tax that funds medicare and 12.4% social security, they pay % on cap gains.It's a pretty good deal really. As your cap gain tax on the $500K in dividends is is 15%. Much petter than paying the "little people" employment expenses PLUS income tax.
So the answer to your question is not very many people have 7 figure W-2's. Folks that are making $1,000,000 a year as an employee, usually have a lot of comp coming to them in stock options. Which has the same effect as shifting income to a dividend payment rather than W-2. The exception on that million ins W2 income are likely on the East coast in finance, and the west coast in Tech.
But if you are working for somebody else in 95% of the country, and hoping to hit that $1,000,000 W2? You probably should have taken your $500K salary and started a business that would produce that same $500K.
