That&#x27;s not how tax brackets work.  You would &quot;only&quot; keep 27% of your income over $10MM, but you would keep a much higher percentage of that first $10MM.<p>&gt; would you put in a million dollars of effort to net a quarter of that in return?<p>Even if I was paying 27% on the first $10MM, putting in $1MM worth of effort would get me a return of 170% per year.
