Having worked with lots of Filipinos on a cruise ship, I can say this is absolutely true. The Filipinos worked as maid staff and deck staff and were truly wonderful people who sent every dime home to their kids and worked harder than pretty much everyone else on the boat. Some of my friends on the ship were moms who had to be away from her children for 9 - 12 months at a stretch.
But that this is the condition does not make it right to exploit them. (Which, I can't say for sure if this company will or will not be doing so - I don't have enough info.) Many of these overseas positions keep your passport, which essentially means you are at their mercy and even if you want to go home because, say your father died, you can't. Many women from the US have been trapped in Japan in the past even long after they fulfilled their contract obligations. There are numerous positions for the leisure industry in the Middle East, especially for American women and some actually pay very well, but they all make you surrender your passport which to me is dangerous.
So, I'm not mocking the people who take these jobs but am disgusted with the way some (not necessarily this employer in question) takes advantage of these people and essentially enslaves them.
By the way, many leisure job placement companies prefer Brits to Americans because Americans demand too high salaries (I blame that on the cost of paying for your own health insurance when working these jobs.).
