That is just true every time you have someone enter a totally new field of work.
Just compare it to engineering disciplines. Imagine a civil engineering bootcamp, 6 month of that, some motivation and coaching from your coworker is enough to evaluate the structural soundness of public infrastructure?
I think you completely underestimate how high the barrier to entry is for engineering disciplines compared to software development. The high pay for software engineers in the US is a phenomenon that is driven by absurdly high demand. For no other discipline is the barrier to entry so low and the reward so high, even outside of the US this isn't the case. In Europe software development is paid very differently.
