You cannot separate government/political system from the market. The stable/productive market is a product of stable and rational system of government. And we do not know what will be in 2032 - extrapolations rarely work in the historical process over long periods.
Ok, no guarantees. I can still spend my privately invested money better than the government. If we can shrink government by, for instance, not allowing them to waste my Soc Sec contributions, we won't have such a large drain on GDP in 2032.
Still, no guarantees but taxes and dying.
