In your proposal, how do you expect the 50 or so people that can afford the extra $50-70k to get to 700 hours to teach thousands of students?
I don't much care for most of his takes, but his polemics on this one are on-point. If I were engaging in the same, the answer to your question would be: figure it out, go time build somewhere else.
The subtext behind your representative complaint
is the original sin: the airline-centering attitude that time building for a 121 job is ok, but not for an educator/developmental role. Remember the pearl-clutching about PFT in the late 90s/early 00s? Don't answer that, I know they don't. Hypocrites. Most of 'em these days think the Lost Decade was a fake moon landing. As I've been told on here, "thAt wAs a loNg tiMe ago, lEt it goOooo". A wild retort, given we trashed our country's M2 less than 5 years ago to float among other things, airline payrolls for them to stay home; whilst my wife lost RN friends on the front lines. Unreal. And Spirit has entered the chat... or is that too soon? Digressing.
Whether the fair wx fans want to admit it or not, the overriding reason regional FO work has been made livable, was because of the barrier to entry the 1500 rule brought about. People routinely overstate their position in life. Cabotage would single handedly throw most airline pilots, along with the entire underpaid downline of aspirants below them, right back to the IT/engineering/insurance/public-safety/laptop jobs they ran away from. They know it; I know it; but everybody acts like demanding that developmental jobs be afforded retirement-empowering wages is some sort of blasphemy.
Time building is a cancer on this industry, but it is a required barrier to entry for those who seek to protect their income at the expense of others. We're all rent-seekers, when income distributions are organized the way this industry does. If we were a restaurant, only the waiters could afford to go to work. Yet people want to pearl-clutch about food poisoning? Spare me.
When people bite the curb, and seminoles spin through overpriced suburban NIMBY motes because they were following the occupational imprudence the aforementioned income distribution engenders, I'm sorry, but FAFO. Maybe treating trainer role compensation with the gravitas it deserves should be a bigger priority for the "revenue center" employers. If that means more barriers to entry, so be it.
Pilots may have an irrational allergy to desk work, but rational economic incentives still rules the roost.
No buck, no Buck Rogers. Frankly, I'm surprised that dynamic would be taken as a hot take, it's not even unique to aviation work.
