Yet somehow they managed to avoid paying much tax elsewhere as well. Strange.
With respect to Japan and China, a multinational company, an effectively stateless entity (or possibly a state unto itself) can simply move to the most profitable country, thus forcing countries to compete for its tax dollars. Thus, the multinationals, unless resisted via solidarity, will cause a collapse in all nations treasuries.
For this reason, we should encourage corporations to form cartels to avoid getting taken advantage of by disloyal consumers.
