Eh? Who is we? The US? One wheat exporter among many? Did you actually read one single response to your OP?
Oh that is likely to work so very, very well. Never mind you seem to be labouring under the delusion that all of OPEC are the Arab Gulf countries that import your American wheat, (they are not) and the fairly trivial ability to switch to say Ukrainian or Russian wheat. Or an alternative to wheat.
Not only harsh and unfair, utterly catastrophically misconceived. The best case is you merely deprive American wheat exporters of their markets, destroying your wheat exports. The worst case is you pointlessly touch off starvation and impoverishment in non-oil exporting countries.
Nevermind that you’re up in arms about a cartel that does not seem to have real control over pricing either on the way up or on the way down. Again you are labouring under profound misconceptions. There is little sign OPEC triggered the price rises of 2006-2008, and they certainly didn’t want the current price collapse.
And so? Lot’s of things you bloody people do are illegal elsewhere… Welcome to the wider world, not everywhere is America.
Oil is their lifeblood as well, and it is perfectly rational for oil producers, especially ones with little else to export, to maximize the value of their exports to the extent possible. Not that OPEC seems terribly successful at that.
The fair price is the market price. What you want is an unfair subsidy to you, low prices all the time. Oil is a global commodity and desired by lots of different users, of which you people are but one. Now as it happens you have built up, for an advanced economy a rather oil intensive economy. Insofar as oil production has likely reach a plateau relative to growing demand, and future production is just going to get more expensive - that means with or without an OPEC trying to manage demand your “fair price” is going to rise.
Rather than coming up with absurdly naive ideas about using wheat against innocent millions who have fuck all to do with oil production, you should be agitating for research money to go into cost efficient alt. energies, and investing in rendering your economy as energy efficient as possible.
