Not enough time. It’s the business model. People will only pay so much out of pocket, and you need to rotate through a lot of those in one building.
Because it’s really freaking hard to do, requires financing, cannibalizes most upfront revenue, and you have to own the full stack: financing, the school, and outcomes.
Finance people certainly don’t want to start a school.
And to do it really well you have to be willing to handle the full stack - admissions, the school, placement, and finance
And you have to play insane games to qualify.
