Organizations are managed and you will have to learn to manager your financial affairs also. Blind contribution often hurt legitimate charities because blind contributions attract scams, and mal-contempts. To improve the society it is often better to restrict your contributions to a few select well managed charities as the church, and 1-3 other organizations (Red Cross, schools, etc.). For example many beggars are receiving subsistence from your tax dollar and simply begging to increase income. This is a big problem when the beggar could work but chooses not to, or when the beggar uses the money for nonsubsistence, this is more common than you think. Many beggars are feeding cigarette, alcohol, drug, or gambling habits. A couple of years ago a news story broke in which one of the High rollers in Shreveport Casino’s was a Dallas beggar. Certainly not all charities are frauds nor are all beggars addicts but in the greater good it is often helpful to forward charity donations through major charity organizations as those mentioned.
Also you should know some other problems as 1) When you reply with a blind donation your name is added to a target list and SOLD to others. So the more you give the more you will be asked to give. 2) As a managed business any reply promotes more activity, thus the effective management of these activities is to not reply at all. 3) When you select organizations to give to anonyms is the best method- any bank or check printer will provide you blank “temporary checks” which can be used. If you mail cash be sure to wrap it in a piece of paper to obscure it in the envelope
