The Multiplier effect is true but it is too naive to apply to complex economic realities.
Firstly, there is a salient time gap between government spending (I) and
its outcome - demand (D): you can't get the effect of government spending right after
increasing it.
What if you can have the benefits of government spending 5 years later?
Like CEOs, economists seldom think applying multiplier effect (mostly Keynesian side)
to the economy - too late to prove they are right. Thus, applying basic multiplier
theories to the current economics situation is somewhat inappropriate.
Secondly, monetary market and international trade can influence our economy dramatically.
Exchange rate or FDA can be rather more important than the multiplier effect.
Thirdly, many US factories are located in China and other foreign countries.
Direct government spending can increase US infrastructure but the effect to
the production company and demand is not decided.
I think we need to compare the economic policy of Regan and Clinton for getting implications.
Reganomics is a kind of supply-side economic policy: They argued reducing tax
rate can increase economic growth. However, this was proved to be inefficient to the US
economy.
Mr.Bush's tax cut policy is similar to Reganomics in a sense. Future? Never know...
However, one thing for sure is that Reganomics is failed. Bushnomics?
remains to be seen...

The thing people do not realize about government spending is the multiplier effect. Those in politics talk of government spending like it's a bad word. Why??? Because they know the average American has little economic knowledge and would never understand the multiplier effect of money throughout the economy. They see it more like their own checkbook and when the money is gone, it’s gone. The truth is that the impact of economic benefit is exponentially greater than the spending. PROVIDED!!!! the spending is on US interests here and works for the benefit of the US people. Cut a $50k per year employee and you have cut far more than $50k from the economy. Shift $20billion from the US economy, well, you have just taken exponentially more from the US citizens.
Multiplier Effect
Initial increase in government spending results in increased income
Increased income [disposable income] is either:
Spent
Saved
That part which is spent [Marginal Propensity to Consume] flows back into the circular flow as consumption.
That part which is saved [Marginal Propensity to Save] flows back to the government
This process continues until the additional savings is equal to the initial increase in government spending
Total impact on spending is greater than the initial increase in government spending
The multiplier tell how much total spending increases as a result of the additional increase in government spending
MULTIPLIER = 1/[1 - MPC] = 1/MPS
