The point of the parable of the widow’s mite was that the mite was all she had but she gave it willingly. I have to say that I heartily agree with Dan Hodges.
It is very nice that the wealthy can decide to give their taxes to their pet cause rather than to the basics our society agrees should be priorities such as defending ourselves, keeping people healthy, etc. It isn’t charity though. Charity is giving what you have. It should feel painful. It should mean you have to go without something. By curtailing abuse of charitable giving taxes will be lower overall and ordinary people will have more money so that they can make their own choices about what they spend.
