You are right that 7 figures annually is different than just 7 figure net worth. However, if you have a 7 figure net worth, you could probably get to 7 figures annually relatively easily.
something to reasonably expect, might be be a 4% real return (i.e. net of inflation). that's achievable with discipline and no skill through low fee passive index investment. luck of avoiding catastrophes would also help.
at 4% real return, assuming you paid zero tax, your wealth doubles roughly once every 19 years. To throw off a 7 figure income at 4% real return you need $25m invested. That's 4.6 doublings of your initial $1m, so after 80-something years you're across the line. better start early.
Another way to accelerate the journey is to cheat and convert your money into a currency that is extremely devalued, then your income can have many additional figures even if your wealth is unchanged.
I wonder if growing a successful 7 figure income is easier than becoming a 7 figure exec.
Besides, by being a 1M small business you're solving problems for society, by being a 1M per year top exec you're probably at the level you're bribing politicians, brainwashing people with ads and woke marketing and generally making the world a worse place.
Any director at FAANG will make that much.
Then your priorities are probably fucked. Assuming this isn't just a devil's advocate hypothetical.
