Employing domestic helpers in the Philippines is it wrong?

Domestic helps in the Philippines are they a victim or part of the economy? It is something that I have debated over previously as we do maintain domestic staff in the Philippines. Be it for laundry, live in maids, nanny’s, drivers taking the kids to school all are domestic workers in some way. But the reality is that the market dictates what people will pay. But also when assessing if someone is underpaid people generally don’t take into account the real cost of living. E.g. you see charities doing it all the time talking about people living on $1 a day.
What they don’t mention is they own their own property, live off the land, free education and in reality are not as bad off as people imagine.
