Too bad, I want less. And lower taxes.
So how much does complying with regs bump up the retail price?
Too much. It also reduces production, employment and competition.
Prove it. I have looked many times and found very little information on the cost of compliance with EPA regulations. Hard facts; I can find little. My guess for manufacturing is less then 1%. But to bean counters 1% is cause to do radical things like move a factory to Mars if need be.
