Miners incentive is obvious here, and it is sad that there is no other actor with power to balance this. Of this is about profit, not the network health or usability.
Nope , miners an pools will work in any case , either fees are low or high , of course profit maximization is a plus for them ( find me a business that's against that ) . Those that were looking forward for such high fees as a result of limited blocksize were those in the maxis camp . Btc just gets what maxis wanted , so you should look others than miners and pools to blame .
