If we double the number I gave to $60,000, that's a lot more, and starting to approach life-ruining territory, but I'd say still falls a bit shy of it for an engineer.
The first time I attempted school and dropped out, I started getting a ton of advertisements for for-profit universities in the mail. I knew that they were often scams, so I threw them away, but I can totally see an alternate universe in which I don't know that and end up with a boatload of debt for the rest of my life.
