Charlie:
You don’t get any “mitzva credit” for anything your tax dollars go to; whether it be supporting torah, poor people, or anything.
The reason for this is that you did not have any choice in giving it.
An essential element in tzedaka is that choosing to give it.
One of my Roshei Yeshiva says that one would think that a communist society is the highest chessed. Truthfully, the problem with communism is that there is zero chessed. Nobody is giving of free will.
Robinhood’s victims did not do chessed when he robbed them.
