> The comparison with a private commercial service is flawed, in the sense that engagement with it is an entirely personal choice. That's exactly what a lot of people are up in arms about, they get taxed hugely but get no real say in how the money is spent. Sure they get a vote, but if your candidate loses it's not as though you're exempt from paying taxes. In some way these people are right; if they choose to engage in commerce they aren't being forced to do anything and as such "whatever the market will bear" is a good metric. Taxes aren't about "whatever the market will bear" though because you don't have a choice to not consume and therefore not pay.
