For instance, it says total UK liabilities are 1000 times gdp, but past gdp growth over the same duration those liabilities are amortised over is 3000%.
Past performance would suggest this seeming over committed will simply be eclipsed.
There is no guarantee gdp will keep going up, either globally or in particular countries, but it does indicate that, growth is the way out and we should places our bets there.
As recent small state low tax economic policy has failed to deliver growth like we saw under bigger state higher tax policy, maybe we'd be richer if we reverted to that.
