The fact remains though that if you don't force a lot of companies and big businesses to improve environmental things, especially at a cost, they won't do it. They'll lobby as much as they can and fight tooth and nail to save their bottom line. Look at the ozone destruction and recovery. That's a real, tangible change and it was done via regulation. The aerosol industry greatly disputed the effects of chlorofluorocarbons. Look at this trash: And today? It doesn't even matter. We have all the same products, but they aren't destroying our ozone. Then look at the automotive industry. When fuel economy standards didn't get stricter there was no incentive to invest in improvements. Once things got tough, voila, fuel efficiency starts going way up again. And look at VW. They decided it was better to break the law than just make lower performing cars and increasing cost. It's not like they couldn't make their diesels cleaner, it's that they didn't want to for business reasons. When it comes to the environment, big business will destroy the Earth before they give up profit. Environmental regulation is extremely important and we should be thankful for it rather than complain about the loss of good sounding engines. Without strict regulations, you'd live in a poisonous environment just like many developing Asia countries. Do Ferraris contribute to emissions much? No, but oh well. I'm sure if the exotic car industry came up with some sort of tax penalty/funding for clean research, they could negotiate a pass. How about a 200% tax on Ferraris that gets reinvested into clean energy R&D?
