You're jumping to conclusions. I often asked for raises and tried to negotiate. I quit companies several times after they failed to promote me or they failed to give me a raise. I'm pretty sure it has nothing to do with business skills. Just bad luck.

My last boss was so upset when I told him I was thinking of quitting that, in front of the whole company, he threatened to throw me out of the window but then he apologized multiple times and asked me to come back after he regained his composure (I had a lot of leverage at the time)... But I quit the next day to save face and find better opportunities. This company had tons of money (millions to spend on development) but they wouldn't give me a 10% modest salary increase after 2 years of excellent work. That's the kind of irrational people I worked for. There was no indication they were going to be like this when I joined. You only find out about this stuff after several years and then you already wasted your time and have to start again at a new company and hope that your next employer will be fair or rational at the very least.
