A lot of legislation is about "feel good" policies, which are intended
to win over the gullible, but, those gullible are not smart enough or knowledgeable enough to understand that, there will be consequences.
Yes, there are consequences to everything, but, the environmental movement and the massive number of regulations that government has enacted to deal with the environment, have, for the most part, been detrimental to all economies where they have been implemented.
We can have good policies and we can have bad policies, but, the one clear thing is that, the more government gets involved in running our lives, and the more government gets involved in trying to dictate to businesses on how they should run or what they should build, the worse it is for the economy. That is being witnessed all over the country, and even around the world.
You aren't too keen with observing what consequences are, and how it's more like a domino effect.
The people might be looking for smaller cars, but, before that, came the regulations which forced the car makers to make the smaller cars, because, government wanted to force a higher MPG standard on all car manufacturers. And, why are people looking for the smaller and higher MPG cars? Because gasoline prices are very high, and people dont want to spend so much on fuel, with are more than doubled in 4 years. So, what is the major cause of higher energy prices? Again, it's government intervention into the energy sector, which prevents the oil companies from drilling within the U.S and off our shores. That causes a supply and demand crisis, which forces the oil companies to go to other countries to purchase the oil, which will cost a lot more than if it were produce here at home. Foreign oil causes our higher gasoline prices, and thus, to try to reduce our dependence on that foreign oil, our government has demanded that car makers make better MPG cars, and the easiest way to do that, is to make them smaller. That is not what Americans wanted, and it was forced on them by government.
Think, and think again, because, you failed at following the causes and effects, where the effects are the real consequences which you don't understand how they wee caused.
