well Toyota lobbied back in the early 80's to push towards stricter EPA standards because they knew that would cripple the US auto industry- which fueled dozens of other industries. We have seen what that has done to our economy in the north. Now, when it come time to buy a car, people will go buy a car from someone that paid our own representatives to pass laws to ultimately us.
You are right, people will look out for themselves, but that's not saying it is right. I don't think it's right that Nissan and Toyota lobbied in the early 80s spending over $100 million dollars that ended up in pockets of lawmakers to pass laws that favored foreign automakers and hurt US automakers. That is bull , and buying foreign products when you have a choice is siding with that.
But it's not just cars. It's everything. Cars is the easy one because it is so obvious and the US auto industry fuels the steel industry, the rubber industry, banking, everything..
