They've been on strike themselves this week. Some of their staff are in the lowest 20% of wage earners in the whole country.

They, the normal staff I mean, not the bosses, will tell you without hesitation that the system is designed to fail as well. Which is why they've asked for either:

Ofgem to be abolished, the whole system is renationalised and the staff are redeployed to socially useful work; or
Ofgem to be given real powers to impose actual price controls - they couldn't impose those now even if the committee of bosses which decides these things wanted to, because of the legal framework it operates in.

The government doesn't seem minded to do either, however.
