"I personally talked with a security-guard who held tow bachelor degrees one in marketing the other in Economics, and a Master degree in English literature from his country, and now he works here as security guard for as little as QR.1500 per month."

How is that Qatar's fault? I know of that security company, and I also know / can guess the country as most of their staff are from a certain Eastern African country. Personally I have friends from the same country who have just one degree, working here for more than 10 times the pay of your security guard friend. Stewardesses, Cargo operations, aircraft maintenance, teachers, embassy staff etc. So I guess your friend got the wrong degrees.
