I've become very cynical about organizations whose members solicit donations, especially in the name of needy children. MOST U.S.-based organizations are pure scams, with more than 90% of such funds going to professional fund-raising businesses ("Children's Cancer Fund," etc.).
Though I am sure that Bruce Wheatley is a legitimate spokesperson for his projects and that donated funds are used, mostly, for what he represents, I would recommend caution when considering significant donations to any such organizations in the Philippines.
I was associated (did paralegal work) with one such organization based in Angeles City and Sacramento, U.S., which I believed to be most sincere and legitimate. But as I became more familiar with the people involved and the small numbers of actual children, it became apparent that donation solicitation and financial support of the staff were the primary activities. There is almost a subculture community of such people in the U.S. who stand outside of Philippine businesses, often with tables and ingratiating smiles. Their fund-raising forays, on a daily basis, are an income-generating ritual, of which they seem to brag about and are reluctant to seek REAL employment.
If you really want to help any such organizations, do some research and ask questions whose answers can be validated.
