That simply isn't true, and my opinion has nothing to do with this.
20$/Hr x 40 Hr/Week x 52 Week/Annum = $41,600.
This means a two person household of high school dropouts would have access to an $83,200 income. That is higher than the median for the entire USA. The reason this isn't happening in other nations is multifaceted, but includes lower standards of living (yes, even in the EU).
Again, don't take my word for it:

And before anyone protest with respect to California explicitly, please see #6 on the list above; their median household income is $85,300.
Are you really going to bother with High School and College for just $2,100/year (before taxes)? Do you know what college costs? Consider the extra 2 years of High School alone cost $83.2k per person, it would take 39.6 years for the college degree or trade pursuit (at the median) to catch-up BEFORE whatever time and expense they incurred. And this completely ignores investment potential of income over those 40 years. College would, literally, never be worth the investment for over 99% of the nation.
This entire bill is nonsense. You can no more generate wealth for the lower quintiles via legislation than you can increase national wealth via legislation. It doesn't work that way, or everyone everywhere would do it and everyone everywhere would be wealthy.
