It's rare I agree with 100% of what you write...but you NAILED this one. The biggest thing I see now is what another tech said to me the other day when we were discussing the state of the repair industry. He said people now seem to feel the have "the right" to free automotive repair.
People don't put VALUE on having their vehicle maintained or repaired. It's strictly an expense when it should be viewed as an investment in their continued employment...if they miss work enough times due to a broken down vehicle, they will be unemployed.
The real problem is greed.
Across the board greed.
The manufacturers sell vehicles based on them being "maintenance free" knowing their service recommendations will likely just get the vehicle out-of-warranty. They don't care if the vehicle breaks in half 2 days after the warranty ends. not their problem.
100K mile spark plugs/coolant/trans fluid? WTF?
The parts seller/builders are all about profit. Could care less if it fits or works equal to the original. Max profit is all the matters.
Most techs are the same. Don't know how many times I've heard "i'm not gonna do all that" when told they had to remove something to access the part they are changing. Get a bigger pry bar or just throw a half-dozen parts at it. One of them HAS to fix it, right?
