I'm wondering if maybe there might be a correlation between unreasonably high taxes and tax havens? If the tax rate is reasonable, say 20-30%, then I probably won't bother trying to evade taxes myself and I won't have much sympathy with others doing it (greedy assholes!). However, if the tax rate is like 70-80%, then yeah, putting some money in a tax haven becomes tempting and I will have much sympathy with other tax dodgers.
