Going back to school when you’re employed means debt, earning way less or nothing during your bachelor or master, stress, opportunities you’re not aware of because you’re simply not at your workplace anymore
Don't quit your day job. Do school in your non-work hours. This is how I did it. I stayed professionally employed and I went back at 30 years old. I did school for about 3 years part-time to get a 2-year Associates degree. Because I went with Community College and did only 1 or 2 classes per term, I never had to take on debt.
I used that Associates degree and got a better paying job that also came with a tuition reimbursement program. It paid 75% of books and tuition up to a certain dollar figure per year (IRS limit). Again, because I was going to school part-time in my off-hours, I simply never exceeded that IRS limit to extra the maximum reimbursement. I finished by Bachelors degree before turning 40. Again, I graduated with zero debt because I kept my professional employment and used the tuition reimbursement benefit. With that Bachelors degree I was able to get an even better job which lead to significant pay raises in the years that passed.
So, I disagree with your original premise that going back to school as a working adult has to means unemployment, debt, and loss of income. I'm not going to say what I did was easy, but what I did a little while ago is also still possible today. I have a close friend that is a year older than me that got his Associates around the same time I did using the same "keep your day job, do school partime" method, but he didn't start his Bachelors when I did. However, he did so later. He graduates, getting his Bachelors, in two months from now!
