walaoeh, you sound like a decent guy who just got off on the wrong footing. imho i think your main issue is not no masters, but having a too high opinion of yourself. you seem to be an average guy with average intelligence, but keep thinking you are top 10% and benchmarking against top 10% in high finance.

you should focus more on trying to move up in your current profession rather than waste time studying and restart from scratch again. so far it seems you have no real passion in banking and getting an entry level job as an analyst doesnt seem too far from your job as a management accountant. i disagree that management accountant is a dead end job, plenty of people have moved up the career ladder in corporate finance, so it is definitely not a 4k dead end job.
