I could go on about this for hours but I'm not going to, I've got other things to do.
I accept there's machinery purchase, chemical purchase, wear and tear, fuel costs, tax, NI etc etc but I really cringe when I see people on here charging £300 or more for 3 hours work.
Whilst I accept Mikes comment about the value of a surgeon making you walk again, the other end of the spectrum is that in all honesty this is a unskilled profession, it is manual labour and anyone with 2 brain cells who work out common sense can make a living out of it. How many of us would be honest and say we don't have the memory skills, outright ability and enough money behind us to spend 7 years training to become a top doctor/dentist/barrister etc. Yet we some on here earning more per hour than those few examples. (Or at least they claim to be!)
We are only worth what people are willing to pay us, measured against the value of the goods, measured against the time and effort needed for them to do it themselves.
Like Steve I'm too an ex mechanic but I begrudge paying £70/hour for something I can do myself unless the job is quite major and requires specalist eqiptment and a lot of time. Old cars were a doddle whereas new ones require electronic diagnosis machines. Carpet cleaning requires spray, scrub, suck with the odd slight variation of course. End of.
