Lincoln's use of 'charity' here refers to an attitude of forgiveness rather than a redistribution of material wealth.I suspect we both agree with him. Equating charity with redistribution of material wealth is a more modern concept. Example: having forgiven the Germans and Japanese after WWII, the US proceeded to rebuild their lives. If people can similarly forgive the millions of Americans who lost their jobs rather than blaming and punishing them... the next part seems clear.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
