It is my suspicion that the government would prefer that people NOT give to charities, and instead people in need HAVE to rely on the government for assistance. Most good private charities are MUCH more efficient operations than any government program. We also give a great deal to charity (much more than the Bidens do each year, according to their own tax returns,) but would not be able to give nearly as much if we weren't able to get a tax deduction from it.
I think both the charitable contribution and mortgage interest tax deductions should be untouched. We wouldn't have bought a home if we had even thought it possible that the mortgage interest deduction would be revoked.
