Is my anger a waste of energy?

I am confused.

There has been a lot of media attention over the rising electricity and gas prices over the past couple of years.

The price hikes have been blamed, by the providers, on increased energy costs - presumably due to diminishing supplies and the problems in the middle east.

SO, this is where my confusion comes in. How come all of them are boasting a rise in profits, some of which by nearly 50% and some of which their highest profits to date.

They say their great new profits are due to rising energy prices.

Can anyone else see a massive discrepancy there?

Prices are going up as it costs the providers more to supply. Their profits are going up because energy is costing us more. So they are increasing prices exponentially to make higher profits! Cunning, cheating bastards! Seems to me like they are using higher energy prices as an excuse and raising prices far beyond what they need to.

I hate capitalism (in the most part).
