Interesting thread. A lot of new sound mixers (like myself) are afraid to ask for too much I think, but don't want to be stuck with minimal gear not suited for the job like a zoom recorder (mixing? what mixing?!) and a crappy mic. I'm getting to the point where I'll have to ask for more in order to get the gear upgrades I absolutely feel I need (better lavs/transmitters/receivers/ and maybe a smart slate), but I don't think there's any direct meaningful plot against the more experienced of the industry. Low/no budgets can't even afford much over a few hundred a day.
The truth is it's hard to become more experienced in this industry unless you 'make the leap.' I did a few free gigs here and there. equipment was mostly provided and random booming jobs, but I couldn't sit around and wait for an apprenticeship or something that will never exist. I have the foundation from school, my own years of recording random things, shit internships, and my own research. I felt the need to get my hands dirty and am learning everyday.
I agree though, undercutting big jobs isn't cool.
