I don't know if you read that thing about the proposed pied-a-terre tax that NYC is proposing, but it does seem like it would address some of the issues that the city is facing. In general, I have the feeling that breaking down borders is one way to resolve the financial fuckery that seems to be in fashion for both monied individuals and corporations. This E-Estonia thing seems to want to contribute to that financial fuckery, which I might be fine with if I knew how to take advantage of it, but I don't. I was recently chastised for not having a 401k, which I can understand, though I will say that I did feel obligated to at least try to find a way to exist outside of the confusing and convoluted financial beast the "developed" world rides astride.
