I went to a cal state and paid 7k a year in tuition. 3 years later I am making around 300k TC at a FAANG. Everyone who graduated with me seems to be doing pretty well judging by LinkedIn.
I know several people who have succeeded in tech in staff+/leadership roles without any college degree at all!
In law, and medicine, and academia in general? Sure, your pedigree matters. But in tech, and in many engineering fields, a state school degree is all you need.
Just look at the numbers. If it was so easy, again, everyone would do it. It's not.
I saw this with my own school. I have a hard time finding any graduates from my program who aren't gainfully employed right now.
CS degrees aren't like business degrees. It's much harder. Hence, many don't do it, despite the huge financial advantages of doing it.
