"This proposal is divorced from reality..."

After much posturing, bloviating and arm bending negotiating, a budget will be passed that makes some winners and others losers. That's the reality of any budget.
Like all previous US government budgets, this budget will depend on the US Treasury going to the Central Bank and requesting some credit because politicians always spend more than the revenue from the IRS. And of course the Central Bank will gladly oblige and create the credit/debt.
This credit is magically made up out of the gullibility of foreigners to accept US receipts of debt called the US dollar. As long as foreigners send the US real goods for these paper dollars then most Americans will be relatively happy.
When the "dollar game of confidence" ends, is when a US budget will really matter.
