There comes a point where raising taxes does not increase revenue. Historically, that has been around 18% of GDP. We are at the doorstep of that point right now. Meanwhile expenses are well above 20% of GDP. You cannot pay for all these things without creating massive amounts of debt (yes, even if you tax the rich). There is no financial case for spending other than an empty promise that it will somehow stimulate the economy.
Yes, all that stuff sounds nice. But, the credit will run out and it will run out sooner than most people think. The only politically viable solution is inflation which is why I recommend holding gold or other currencies.
