j1979, you really have no idea, do you? Your arguements are rather off, especially as you can be a capitalist and ethical. If it concerns you then buy fair trade- I try to whenever possible.
And if dustment went on strike the army would step in. Not something that could happen with striking doctors. Not that doctors would these days- you might get a work to rule but our social conscience tends to kick in.
Really- your arguements are flawed and that of a GSCE student and no more.
