That may be it though. Maybe the customer is not paying for everything, and at the end of the day, many EC's are taking these expenses out of their own pocket and are left with peanuts.
That is what happens very often I believe. The wife or a previous employer provides the health insurance, retirement and other benefits and the self employed electrican sees what the rest of the self employed electricians are doing and figures that's how the business is and doesn't believe it can be better.
If he tries to make it better he doesn't have a strong belief in the new idea and therefore doesn't have a positive result. Instead of finding out why it didn't work and trying a different presentation for the new idea he says "it doesn't work in my area, there isn't enough money in that, or it's to much of a pain."
Then he says that might work in some area, that only works in high population areas, the guy at HD in my area will tell people I'm ripping them off if I do that or any number of excuses as to why something better wont work in the face of others are doing it.
Than we always have people that aren't even the feild explaining how or why you should do something.
