treatment and hospitalization of the workers??? well, tell me...

They are issued with HMC health cards for any treatment needed and the cost is covered with insurence.

"can we blame it on the "system" then"

System is in place. Workmen compensation policy is compulsory for any construction company undertaking projects in qatar.

at least at the end of the day, we can go home and have a sense of fulfillment that we were able to "extend a hand"

That is your duty. you are paid for it.
