if you want to work on planes, then you do it! Money isn't everything, enjoying your work is. If you want to work on light a/c, then you aren't likely to be facing the pressures that the above assembled have mentioned. Everyday I get frustrated with 'idiot's' in the company I work for, we all do. But, I love doing what I'm doing. I would suggest finding your local general aviation centre and writing to a few of the companies there to see if they are willing to have a chat over a cuppa about their business. You should get good advice there.
Good luck!
