I agree with your sentiments..What happen in many cases is that they have paid mpney to "agents" to get the jobs, and many are in debt when they arrive.. So, they are unable to just resign an leave...

I do however believe that many Indian, Pakistani, Bangladeshis etc don't paint a true picture of life in Dubai / Qatar / Saudi when they go on vacation, thus giving a false image...

Lastly, the Embassies of these countries must also take some blame . They should do more for their people..
