We could probably eliminate all corporate subsidies, almost all agricultural subsidies too.
Actually, I'm glad you brought that up as I notice those terms get interchanged for what ever purpose it serves at the time (not by you but by hacks promoting a given agenda)
My understanding is that subsidies can be tax deductions for business, tax breaks designed to give incentives to businesses to invest, monies given to certain industries not to produce to keep prices up (Jane Fonda's ex, sugar, corn, etc)
I really need to study this more as it seems to be a term that has several meanings.
In the end, I believe a flat tax is the way to go, no Corporate or business tax either as the consumer pays for it in the end anyway.
