I'll slightly disagree with the view about "the race to the bottom".
Most of the market is always in the bottom, whatever the market is. Upwork/elance/whatever just make it stand out.
Most of the work is low paying shit by shit clients who have no clue what they are doing. (Nothing special. It's the same with physical companies to physically work at :D).
As a decent freelancer who wanna do decent work for a decent client, you've gotta filter aggressively.
