Think you are missing the point slightly.
The purchases I make aren't small cheap objects they are in the $70-80k range per item.
My company along with all the big players in the same business all source their products from the same company or group of companies so we have a very limited choice in our supply chain.
I get your last point, however I could say the same thing probably about most of the electrical items you have at home.
Is your TV viewing pleasure well worth the employees who suffer manufacturing your set worth it so you can sit on the sofa at night and relax?
It's the same for pretty much all cheap and high end electrical goods that most of us use everyday.
We are all guilty in that respect somewhere along the line, however a majority of people are happy to be blinkered in the belief that their shiny new gadget comes from a shiny shop somewhere in their home country.
