Taxing income , and sales is a traditional form of financing Government , as long as our Government has another option they will abuse it. Taxation must be qualified , where spending oil profits is easier to get away with. Now they want to dip into the other easy resource rather than ask for the money to support government for the people. They work for the oil companies as long as they're spending oil profits. It's just that simple. Taxes must be negotiated with the people, oil money is taken at will , with no oversight at all.
