As for guys flying for money, just make sure that pilots are being monitored for fatigue and make sure that there are stern penalties if you show up for work just for the money, when you should be recovering.
And how well has that worked so far?
Sensible limits are all that will work. Current FTL's are illogical and dangerous. Fix them and aviation will be safe. Link them to money and there will be many more accidents.
The proposal is a classic example of what not to do.
