Most definately and I think it's all a matter of perception. That is to say they widely held perception in Phils that we are all so rich in this country and whatever we send, we could send much more.
I think what also causes this is that there is also a certain amount of guilt by the Filipina's who are married to Brits and live here about this. I think that many think they should scrimp and do without so they can send more and they feel guilty about our (compared to Phils) indulgent and extravagant lifestyle here in the UK. This can lead to friction with a westernised husband who is used to being indulgent when it can be afforded.
Personally, I beleive that the only way round it is to set an affordable amount that you will send per month and stick to it and then when emergency requests come along, they should be considered firstly by affordability and then on merit.
I have read many threads on this forum where people have said they send what I consider huge amounts of money and I think that giving so much just leads to dependancy. Wherever possible you should offer help not support.
