I agree if you like 'things to do and places to visit' you would be bored rigid. I am a lover of places like Tuscany and the Dordogne, but every now and again (esp. between Xmas and Easter) I need a week in total luxury, doing bugger all! I don't think people kid themselves that they go for anything more than that.
I first went to Dubai about ten years ago, then went back about 6 years ago. I must admit we really noticed a change for the worse in between those times so I really wouldn't go now. I wouls still jump at Abu Dhabi, Qatar or Oman etc though, if I just needed some sun and some rest.
And as far as exploitation of poor migrant workers go, yes, it's hideous. But it's equally or perhaps more hideous in their home countries - which is why they go to the gulf states, in spite of everything. If you went to India or China now you would find very similar conditions for blue colour workers and labourers, just like it was in this country around the times of the Industrial revolution - pre unions, pre-votes for women, pre-education for all, pre-national health etc etc. It wasn't that long ago that we sent children up chimneys remember.
That's why India and China are becoming the new economic superpowers. Rightly or wrongly it wouldn't be happening if their workers all had the same rights and safety standards etc as we can expect here.
I'm not defending it in the slightest, but it is a tad unfair to make out it only happens in Dubai.
When we went to Egypt the woman working in the spa was a lovely Chinese lady who had left her 15 year old son at home with her mother - she hadn't managed to go home for several years. Her husband had been murdered in China when her son was just a baby. Personally I blame China for her plight, not the owners fo a spa hotel in Egypt!
