It's not a good time for any field, and skilled and unskilled auto techs alike are feeling the heat. Most customers can't afford anything but regular maintenance, which is not profitable for the shop, so you have a lot of experienced guys with $50K + invested in their tools doing oil changes and tire rotations all day. If you're on flat-rate (commission) this means you hustle for 8-9 hours and get paid for 6-7, making much less than your hourly rate. It's very frustrating for everyone. Plus factor in that there is less easy, profitable long-term maintenance work necessary for vehicles (spark plugs, drive belts, etc) and it just seems to get tougher. After 2 years as a tech myself I'm starting to suspect that employers really just want a bunch of low-paid parts changers and believe that cars diagnose and fix themselves. Not a good time to be going into this field.
