You could argue that by bringing Filipinos in you lower the wages, and as a result, the native population is less interested in taking such jobs, besides lowering the "status" of the job itself.
I was recently looking for a nanny in Spain and most applicants were Spanish females. Despite that, most parents seem to hire foreign nannies from LA because it's cheaper.
That said, it's really sad if the elderly in Belgium are being taken care of by people they barely can understand. What a nice ending of life!
I remember from my time in the Netherlands that the elderly there get regular visits from a specific person whose job is to socialize with them to solve some of the "loneliness" problems. I wouldn't be surprised if something similar happens in Belgium, which is IMO, a growingly anti-social society.
In Spain (which has the highest life expectancy in Europe by the way) many old people are still taken care of by close family members, or in other cases by people from LA who at least speak the same language. I didn't realize how fortunate they actually are.
