>About 1,000,000 high school players {1}

are high school kids forced to play football and do nothing else? a high school offers you many avenues, not just a pathway into the nfl. mentioning high school is not relevant.

>About 250 new NFL players each draft class. {2}
>Median lifetime earnings for NFL is about $3,000,000. {3}
>

according to your own source, median earnings for an NFL player is $3,000,000 OVER 3 YEARS, that's 1 million per year. i'm not sure why you included the word "lifetime". when your career is over, your professional life isn't over, you can continue earning using other avenues in your "lifetime"

>Making a HS players chance of going pro about 0.025%
>(1,000,000 / 250 = 0.00025).

how is this relevant? it's clearly not easy to become a professional athlete but they don't pick people at random like lottery balls, the players are evaluated according to their attributes and skills. the cream rises to the top. this is true in every field or human activity.

>
>Your expected earnings, as a player good enough to play in
>high school, are therefore $3,000,000 * 0.00025 or $750

again, with "lifetime", when the median is 3 years, not an entire lifetime.

>code and expect to earn something like $2-3 million lifetime,
>conservatively. (30 years x $85000 {4})

based on your source, a football player makes $3 million in 3 YEARS compared to what a coder makes in 30 YEARS. what would you do with 3 million after 3 years of work? i'm sure you have many good ideas.

>This makes e.g. computer science a roughly 3000x better career

no, that's incorrect because you took a median of 3 years and calculated it as a complete lifetime, assuming a football player with a large sum of money has no future prospects, or education, or ability to use those earnings to build a good life.
