The solution is an emergency hard fork to another mining algorithm which renders so all of the miners' equipment useless. This has been discussed before and it is a solution if miners were to be colluding to the detriment of bitcoin.
I think that is not really going to be such an easy thing.
Miners need to turn BTC into fiat in order to do their business (i.e. pay for their electricity and other costs) - but exchanges need the miners to have a steady source of people wanting to exchange.
If devs wanted to "cut out the miners" then exchanges would be screwed for income in the short-term at least (as many of them are partnered with mining pools) so I can't see the exchanges actually likely to agree with such a change.
I suppose it is more of the threat of a hard fork which cuts out the miner's is what would persuade them to not abuse their power.
