They will probably increase their profits, by finding methods of marketing to kids at increased prices like the tobacco and alcohol industries have done for ages.

Ad hominem.

I agree with you that this has happened, but it is far from the only reason that vehicles have increased in price. Now almost every vehicle comes with power windows, power locks, power mirrors, at least one if not multiple built in tv screens, wireless locks and keyless ignitions. Not to mention alot of manufacturers building in computer hardware/software to track user information and installing propietary parts/hardware/software designed to keep your local mechanic from doing repair work and forcing you to use dealership mechanics at 3-4 times the cost.

All of it is being done because it makes more money. Mark my words, if they repeal safety regulations, it will definitely reduce the safety of our vehicles, but it will have little to no effect impact on prices. I would wager my left nut that auto manufacturers are chomping at the bit to get this deregulation put through so they can reduce their cost of vehicles by increasing the danger of the consumer, but wont reduce the prices by a fraction of what they are “saving,” then will proceed to have record profits while using lobbyists to pay off our crooked politicians.

Id even be content to let the eight figure incomes slide… at least at first. Lets start with the 100-200 dudes that have a ten digit income and work our down… the tens and nines might be enough to fix things and still leave us with plenty of ultra rich to complain about.
