But would you pay for a another, say, French Navy or Turkish Navy aircraft carrier? There are few things which western democracies spend taxes on which don't benefit at least some proportion of the tax-paying population, and most of the cost of running those public services also goes back into private industry of the same country. A private internet company can employ foreign workers, pay foreign taxes, award dividends to foreign owners, and after all that, can be just as corrupt and expensive as a tax-funded service!
