This may sound horribly theocratic, but I believe that Trickle Down economics may have its best efforts showcased in the church. When a man with means can freely give to those less fortunate, apart from government legislated giving, he should do so.
Indeed, rather than trickling, the money should pour down....freely given, and allow those with less to be blessed.
Then maybe they will catch the spirit of generosity and bless others as well. Ive seen it happen time and time again at my store when we solicit (its our job) for charity. You see all kinds of givers. (or keepers)
Some with means wont give a nickel. They only give at the end of the year, so they say, in order to write it off.
A few give generously, but what I have noted is that it is often poorer (as I judge them) families that often give the most. By and large, poorer people are more generous than wealthier people.
As an aside, a corporation is allowed a larger corporate tax break for charity than individuals receive. Thus what they essentially do is donate
your donations and get it written off their expenses.
