The thing is that I don't have much choice when it comes to, say, electronics or the clothes I wear and so on, but I'm not the person who employs the people who make those things directly and I don't profit from their work. In fact, if you think of it this way, if I pay £15 for a cardigan made in Bangladesh by a woman who gets paid £5 a week for her work, I'm getting ripped off also. Why am I not paying pennies for it, if that's what her work is worth to whomever is selling it to me?

Your position, however is different than mine. In your case there's noone forcing you to not share a bigger part of your profits with the people you employ. The choice is all yours.

You maximise your profit. Fair enough. But that brings us back to my original comment. In a free market economy, everybody is maximising their profits. For low-wage workers that means minimising the quality of their work, and I don't see any way out of it, if you agree that everyone is a rational player.

The alternative is that you're hiring complete idiots, which also works to your detriment, considering they're expected to work with their brains.
