Instead, this is a moral question about whether people have some sort of obligation to pay extra tax, merely to get some sort of pat on the head from politicians. The same politicians, by the way, that squander the money on varying vote-buying schemes that undermine prosperity and create dependency.
I’d be willing to condemn Carr if I found out he’s some sort of statist who wants higher taxes for everybody else, but then (like John Kerry) takes steps to minimize his personal tax bill.
But I’d be condemning Carr for hypocrisy, not criticizing the idea of tax avoidance.
The United Kingdom has become a bloated welfare state (with horribly depressing implications, as you can read here and here). If people want to be moral, they should strive to pay the least amount possible to this corrupt and wasteful enterprise. The United States is not quite as bad (yet), but the same principle applies.
Politicians, needless to say, will violently disagree with this ethical viewpoint. So we can all expect more taxes, higher taxes, and additional draconian enforcement measures.
The only good news is that the Laffer Curve will prevent these greedy thugs from collecting nearly as much money as they think.
P.S. To get an idea of how the Conservative Party has declined, compare Cameron’s statist rhetoric to Margaret Thatcher’s comments that “there is no such thing as public money.”
