Its real hard to not be a part of the system. I do understand your point and it does feel better to be further removed from the bad behavior. But most of us are participants.
Dubai had (and maybe still has) widespread problems with slavery and indentured servitude - both are problems not widespread in any of the major manufacturing centers in East Asia. Where the worker in Dubai is hit with a litany of hidden fees upon arrival, the worker in China is not. Where the worker in Dubai has his passport held until false debts are repaid, the Chinese worker does not. Working in a Chinese factory is almost utopian compared to the conditions that have apparently been exposed in Dubai.
My original post was simply finding examples of how people use their spending power to participate in various forms of oppression. Widespread marginal participation is possibly the worst as its hardest to solve. One billion people marginally participating racks up more power than a few hundred thousand oil-rich do.
It's one thing to be forced to pay taxes, some of which may go towards a war you're against, and quite another to go and get rich off the slaves of Dubai (especially if you do it knowingly), or go to Dubai specifically to exploit the slaves (as some of the people interviewed in this article admitted to doing).
Ultimately, it is left to the each individual I guess. If only each one of us decide not to buy products of slave labor, not to support war etc, world would be a better place in an instant.
Would you be okay with "making out great" and becoming rich if it meant that other people had to work in 130 degree heat for 18 hours a day in order to build the buildings you live and work in, and had their wages withheld and passport confiscated by their employer?
Would you think that you had made a bad choice?
To answer this question regarding myself, I don't know. For example, I wear clothes and shoes that are obviously made using horrible labour in third-world countries. Also, what are the people who already live there supposed to do? Halt their lives and livelihoods and move out?
All I'm calling for with my comments is more restraint when it comes to the 'holier than thou' comments. It's too easy to express casual outrage and condemnation on the internet.
Edit: Not sure why I'm being downmodded; all I did was answer the parent's question.
