Did not all this just get discussed in a 6+ page thread?
Ask yourself this about your job. Why use your accounting firm when I can go online and get the same services much cheaper? Why should I spend 40% more to visit your company to get a widget made when it can be done online through a Chinese company at a fraction of the cost? Why should I hire your kid to process paperwork when I can get the same thing done by a younger, more willing person at a much lower cost?
What value does anyone bring to the table that cannot be duplicated at a lower cost elsewhere?
Why tip a waiter/waitress when they are already making 15 bucks an hour minimum wage? Seriously, we just went through all this with no discernible outcome.
