I don’t think Jews will change giving tzedaka much. Even those who used to get a special charitable deduction and will not since they switched to the standard deduction, are also paying lower taxes overall since the tax tables themselves are lowered in addition to the higher standard deduction they’re going to get.
Since they aren’t paying more in taxes under the new tax code, and are probably even paying less taxes without taking a charitable deduction, there’s no reason for Jews to give less tzedaka.
