Um, foreign companies deciding it's not worth the cost to bring all of their vehicles here has nothing to do with a lack of a free market. Heck, it has everything to do with us HAVING a free market!
How so? From Wiki:
A free market is a competitive market where prices are determined by supply and demand. However, the term is also commonly used for markets in which economic intervention and regulation by the state is limited to tax collection, and enforcement of private ownership and contracts.
We obviously no longer have a 'free market' as far as automobiles go. You can't buy a Pagani... they tried, and the government felt it needed to interfere with it. You can't buy a Caprice, or the Holden zeta models because GM claims the costs to federalize it are too high. Its virtually impossible for a small company to enter the automobile market. Tesla and Fiskar have spent billions to get off the ground. Panoz, Mosler, Saleen and Shelby have to fight tons of government red tape to stay in business. According to Wiki, this is a regulated market or controlled market.
Now, I'm all for reasonable safety, quality and clean air, but the government has gone off the deep end and over regulated the automotive market and their heavy handed approach has caused most cars to be uniformly boring and has raised the bar to enter too high.
We can never have a truly free market for automobiles, but we need to take a step back from the crazy overregulation going on right now.
It's not over regulation or under regulation. It's different regulation. In many ways, the European standards are stricter than our own, but because the standards don't mesh well, we lose out on some interesting cars.
