I think we all lose, if we do decide to pay for this entirely through taxing the rich. We (further) lose social trust between the rich and the rest of us, and we (further) lose the sense that we're all in this together, and we encourage ourselves to further think about how we can get those people over there to pay for our stuff over here.

To be clear, yes, please, tax the rich. But do so with a progressive taxation that we all pay into, so we all share the cost to the best of our ability.
