Just so you get your terminology straight.
The "Ethanol Subsidy" is a tax break of 45 cents per gallon. Since 10% of the gasoline everyone uses every day is Ethanol, this gave everyone a 4.5 cent tax break on every gallon of gasoline they buy.
The subject of debate is your list of Big Oil subsidies.
Still waiting for the list.
I had already posted a link, but here is another one for you.
The Wall Street Journal: Oil Demand Growth Vulnerable to Subsidy Cuts
In 2009, the IEA says the total cost of oil subsidies was $130 billion. But in 2008, the last time the oil price touched $100 a barrel, this figure was a budget-busting $280 billion.
That is a link to an article about the oil business, but it is not a list of subsidies.
Still waiting for the list.
