On the one hand, I've never had my lack of a degree be an issue in tech, especially startups. Some founders even place a weird bonus on being a dropout and see you as more of a hustler than degree-holding employees.
On the other hand, there are some opportunities that are closed off to me unless I decide to finish my degree. For example, I would have liked to get an MBA or go to law school for fun, but those options are completely closed off. You absolutely must have a four-year degree.
Another one that came up recently, I've been thinking of taking a break from tech and going into public service, all the jobs I saw in the three-letter agency I was interested in also had a hard requirement on a four-year degree.
A degree isn't necessary for everyone, it certainly wasn't for me and it's nice that I had almost two years as a head start on my career in tech. However, I wouldn't encourage people to drop out.
Having a degree gives you options. You're better off with those options than without. You don't _have_ to take out 200k in loans. There's fantastic public education systems like CUNY that you can take advantage of.
