I'm not sure if you are referring to me, but certainly do not condone 'mass exploitation'. I would say that the biggest issue of mass exploitation, as you put it, is the prostitution, which is actually quite touristy.
However, this is not unique to Dubai or even the Middle East. The iconic photograph of the men building the Rockerfella Centre in New York was hardly compliant with modern health and safety rules, and the ships to the Free World were not known for their comfort, nor were the employers benevolent charities. Times have certainly changed for some but not all.
There are many many millionaires in India but it does not seem to be subject to the vitriol that the Arab nations get, or at least, the RICH Arab nations.
DH was staying in a hotel in Delhi and there was a dead guy jut outside the hotel. When DH raised his concern, the receptionist said, I'm sorry sir, we did not mean to offend.' He tried to explain that he was concerned, to much bemusement. They basically did not give a fuck and were scathing of DH's concern. It is a tough world. Now many Indians travel to Dubai and other places for the chance of work and to send money back to their families.
Pressure should certainly be put on authorities to improve conditions where they are poor but lets not kid ourselves that things are not grim for people from other coutries in other places. Actually India's caste system contributes massively to the ongoing poverty there with very little means to escape it. But we give them large amounts of aid and they have the nuke. And btw, the building sites in Delhi are unbelievable, with women in skirts climbing up bamboo ladders, no hard hards - shocking. But India is ok and hippy and the rich Arabs get all the shit.
