if you're in the USA, you're okay with price-fixing and subsidies because it keeps our gas prices low. But you can't say "I'm 100% capitalist!". You have to say "I'm normally capitalist, but in this case, I support other groups taking less profits to allow me to sustain an unsustainable existence which the market doesn't allow".
IF IF IF Russia, Iran, and China were making threats - in order to force the US and Canada to lower the prices of maple syrup we were exporting - we'd tell them to piss off. This is difference, cause its OUR prices we want to keep low 
Trump has an anti-capitalist position here.
Like everything else America is not pure capitalism, just like we are not a pure democracy. If America was pure capitalism there would be no subsidies, there would be no anti-trust act, and monopolies would fill the land. As usual you take everything to the extreme, to try to make some point that only you know

Oil is a natural resource, more over it is a matter of national security to just about every nation on earth. Maple syrup is not.
Do I have a problem telling the Saudi to quit fucking with price and supply? No, just because their great, great, great, great, great grandfather happened to pitch his tent on an oil field. Hell they wouldn't even have the know how to get the oil out of the ground if not for the innovations from the west.
