RELATÓRIO DE OUTUBRO 2013 DO FMI - Fiscal monitor
The facts which state that the only way to resolve the massive debt load is through a global coordinated debt restructuring (which would, among other things, push all global banks into bankruptcy) which, when all is said and done, will have to be funded by the world's financial asset holders: the middle-and upper-class, which, if BCG is right, have a ~30% one-time tax on all their assets to look forward to as the great mean reversion finally arrives and the world is set back on a viable path. But not before the biggest episode of "transitory" pain, misery and suffering in the history of mankind. [..]
There is one thing we would like to bring to our readers' attention because we are confident, that one way or another, sooner or later, it will be implemented. Namely a one-time wealth tax: in other words, instead of stealth inflation, the government will be forced to proceed with over transfer of wealth. According to BCG, the amount of developed world debt between household, corporate and government that needs to be eliminated is just over $21 trillion.
The sharp deterioration of the public finances in many countries has revived interest in a capital levy, a one-off tax on private wealth, as an exceptional measure to restore debt sustainability. The appeal is that such a tax, if it is implemented before avoidance is possible, and there is a belief that it will never be repeated, does not distort behavior (and may be seen by some as fair).
The tax rates needed to bring down public debt to pre-crisis levels, moreover, are sizable: reducing debt ratios to end-2007 levels would require (for a sample of 15 euro area countries) a tax rate of about 10 percent on households with positive net wealth .
