You should take a closer look at the relationship between the price of oil and inflation. Removing fossil fuels from the equation would cause inflation to go like crazy. The price of oil would plummet (although it would eventually skyrocket again once it's completely obsolete), and it's hard to predict how inflation would react. Normally if the price of oil goes up, inflation goes up. If the price of oil goes down it eases inflation. Not across the board mind but it does still have a significant impact on the highest capital areas of the market such as banks and mining companies.
You think governments are resistent to finding cleaner energy sources because they hate our planet? It's because our finance system is so tightly interwoven with the energy industry that a violent move could cripple the entire world. These sorts of changes have to be gradual. Plus it's kinda nieve to think that corperations haven't been thinking of ways to monopolize new energy sources. Eon already control the majority of wind farm power in the UK and Npower controls most of the nuclear power and make a damn good living off of it. Indeed the worst of are actually those running coal and oil power stations because the price of fuel is too high, but it's too expensive to replace the furnaces with reactors or solar panels.
And seriously, you're putting far too much thought into this, yes many companies try to create gaps in the supply of their products to increase prices, hell why do you think diamonds cost so much? Africa's p***ing the stuff but entire countries are encouraged to go to war to hide these resources to keep the prices up, that's well known. However bankers and other entrepreneurs have nothing to gain and everything to lose from crashing the economy into a brick wall. They rely on a sustainability of the economy, not a quick cash in. If the economy keeps going the way it's going then the dollar will have to be devalued, the bankers will lose massive amounts of money. Why in the hell would they plan that? Seriously, try to learn a bit more about the economy before creating these wild covin fantasies. I've been studying economics and politics for a long time.
