Sorry man, your mostly wrong. I commend you and your accomplishments, and my own background reinforces that FORMAL eduction (getting a piece of ink on a piece of paper) is inherently meaningless.
HOWEVER, you and me do NOT a trend make. Just because X amount of people like us can kick massive booty in the real world without the benefit of a highscool diploma or a college one doesnt degrade the value thereof.
Statistically speaking, a high school diploma is a SIGNIFICANT variable on life expectancy, incarceration rates, income potential and every other metric you want to throw at it, even despite (some degree) of relative IQ. Your employment opportunities are severely limited for each level of academic accomplishment you cant proove, particularity in technical fields and more explicitly for the high school level. Indeed you become almost unemployable.
So while you can say graduating doesn't GARUNTEE success, youo cannot compare that with the likelihood of failure if you dont graduate. in the simplest form its simply a matter of risk management on the employers (and/or clients) side.
Not trying to rain on your parade, but i don't think anyone should be a cheerleader for NON-COMPLETION of scholastic advancement in our society no matter how successful they've managed to be. Should our society change so significantly as to measure a persons worth through other means... then fine. But in todays world it is an UNDENIABLE fact that your level of educational attainment has a very DIRECT cor-relation towards your quality of life and earnings potential.
see below for starters.
average income of HS grad : 36k
average income of masters : 78k
average income MD / ESQ : 100k
average income doctorate : 96k
Average income NO high school degree : 22k
