But the car companies fought it because it decreased theirs.

Don't you see Rob, all these people care about is their profits.

They don't care about you, or the country, or human life, or anything BUT THEIR PROFITS!

Of course, that's not too surprising, human collectives often consider their own benefit before they consider the benefit of the individuals who make them up.
What I can't understand is why the humans who are their victims keep on making excuses for them.

No one blames capitalists for being greedy and mercenary. That's probably not a purely bad thing, and it probably all works out in the long run anyway. But I do blame the people who suffer these crimes and insults for being so stupid they can't see this. They are not doing you any favors when they hire you, or sell you their products. You are doing them a favor when you buy their stuff and work for them. You have every right, no, a solemn obligation, to make sure they don't get away with anything. And you especially have a duty that they don't get in cahoots with the government in order to exploit you completely.

Remember, in the absence of proper government, the strong will ALWAYS take from the weak.
