I know plenty of OFW's here in UK.
Usually they live very frugally. Usually 3 or more together.
They send most of their earnings back home. Most have kids and families to support.
They do it for the betterment of their kids and families.
For education, for homes, for food on the table etc etc.
It is difficult for western people to get their heads around this, simply because we will never have to face a life with nothing or with no state support if we need it, with no
medical or hospital facility free at point of service.
I understand them and I respect them. Even sometimes they know that their own families and husbands are really fleecing them.
