Obama Wants to Spend 50 Billion to Rebuilt Infrastructure

It's around 90%, according to the US Dept Clock.

That's kind of scary, actually.

It depends on what you include. Iraq War expenses haven't fully been recognized (VA benefits, cost of refurbishing the military, etc.). Medicare and Medicaid obligations aren't included. Social Security will be upside-down within this decade. If you include EVERYTHING the US debt exceeds 400% of GDP, but most of those liabilities are just liabilities and not actual spending so we'll never know.
