My experience from a freelance writer's perspective has some similarities with yours.
I joined the industry 3 years ago and joined a company that was paying a CPP range of between $8 and $16.
However, a few months later the site became flooded with writers and so not only were orders becoming scarce but the CPP was lowered to around $5. As if that was not enough they introduced an option which allowed writers to lower their bid prices so that desperate ones would offer to do the papers at much lower prices.
Needless to say, working with the company became unsustainable but I was lucky enough to get another company whose rates were much higher at between $10 and $25. Again, it was not long before desperation set in and the rates dropped to below $8 per page. At this point, I gave up on companies and decided I was much better off working on my own.
As long as assignment research companies get endless supply of writers willing to work at whatever rates, this industry will continue its downward trend.
