Bullshit - technology skills can be learned like any trade. Writing code does not require a 4 year CS degree.

But we are still bound to supply and demand. If everyone was a coder, price would plummet. Programmers are only currently able to do reasonably well because they are relatively limited in numbers compared to the demand for them.

It is very much impossible for most Americans to be coders while maintaining high incomes. The industry isn't anywhere near that big, currently employing less than 1% of the population. Even if it could grow by an order of magnitude, it still wouldn't absorb any meaningful portion of the population.
