Frankly, I would rather see the balanced TRUTH...ie cheap labour for the nuveau riche and upwardly mobile, rather than some airy fairy 'upbeat' tosh, but dumb it down for the masses if you must.
The only reason most of these domestic workers suffer being 'owned' by these people (normally visiting diplomats) is because they are in poverty at home and most likely sending most of their pittance pay-packet back there to support their children and extended family.
Are Filipinos still in fact given visas to enter the UK as slaves....sorry, I mean 'Domestic helpers' ?
