we need more manufacturing jobs in the US and need to start making stuff in house... why is this soooo bad?
Because if other countries can do it more efficiently and trade with you, you end up worse off by trying to produce it yourself.
nice new roads are great.... if only people can afford to drive on them.
Infrastructure such as roads will help boost trade and business, as well as being beneficial for the general population. They're an investment in the future rather than the short term, which is a very good idea - you provide the large injection to boost the economy in the short term, while the benefits of that large injection are felt in the long term, which helps make the impact of the debt repayment (assuming you've borrowed the money) far less severe.
you want to put money on this that the econ should be recovered by that time?
Yes, based on past recessions I think the most likely outcome is that this one will be over in 3 years time.
Chicken?
Showing your maturity yet again I see Doc...
