Yes but what many people did not realize is that the company who employs them are paid for all of them. Remember I was involved in a project to dock a ship for maintenance. I was supposed to check the electrical connections. On the day, 1 Malaysian supervisor and 6 Ah neh showed up for the docking. It's a 6 hour job but on the contract, they are paid close to $100k for the work, supposingly done by 7 engineers/ consultants.
