I’m sorry but you are in error. The vast majority of capital used for speculating is placed by capitalists.
Energy reserves have nothing to do with the spot price of energy or energy futures. Speculators inhibit price volatility over time. I like them very much, they are not villians. The villians are those inhibiting production in the USA and offshore. And even they aren’t hurting us that badly long term. Energy in the ground costs nothing to store and is quite safe there. It will be produced at a higher profit margin some day.
How you can say that with a straight face, given the extreme price volatility of oil over the last three years, is beyond rational comprehension.
Oh, and those capitalists you are praising? Add the word 'crony' to them and get back to me. I greatly appreciate real capitalists who make things (or actually produce oil or copper or other products) and get rich doing it. But the investment banks have turned into parasites, driving up the costs of living for everyone and then turning to the government for a bailout when they guess wrong.
