Flight training expenses have gone up significantly and many of those old 135 jobs are almost impossible to find now, so it's not a fair comparison to bring up the old de facto mins.
The only reliable time building job these days is flight instructing, but you need more people on the bottom starting their training than at the top teaching for it to work. It's essentially a pyramid scheme, and I'm not sure we can sustain it. A big reason we've been able to so far is foreign students. As someone else pointed out, they'll start flying a widebody at 250 hours while you're still slaving away in a 172 with no air conditioning in the summer for minimum wage. To add insult to injury, we're training our future competition.
