The US government is now spending more in real dollars than it did fighting World War II, and critics say the results don't match the price tag.

• Today's total federal budget tops the inflation-adjusted cost of World War II.
• World War II spending was a bigger share of the economy back then, but actual dollars spent today are higher.
• World War II is remembered for transforming the US economy and society for generations.
• Current spending levels are being questioned because the outcomes don't seem to measure up, regardless of whether you agree with what the money is being spent on.

Outlook: Expect more scrutiny of federal spending levels as this comparison spreads, likely fueling pressure for budget cuts or reform.
