I think that's the thing, it's not that amazingly well paid. Considering it only requires a high school diploma and a certificate it pays well, but overall you're probably only making around $38-55k per year. I did find some exceptions such as the upper end of NYC techs making $65k, but even LA had a high end of $55k. Maybe the salary data I saw was wrong, but that's not particularly well paying.
The high paying job is the Pharmacist who is probably pulling in $120-160k, but the tech is doing all the real work.
This guy probably looks at it like they aren't conventionally attractive (which isn't true) and they aren't making stupid high salaries.
Most farming is subsidized, the debate then is which one is subsidized more. A bit of a specious argument at the end of the day.
