"...A more effective strategy would be to try to tilt the economy away from consumption and toward exports and long-needed investments in infrastructure."
Fat chance of that. Faith in the spending power of American consumers would have to dwindle a whole lot before companies stop selling to them.
If infrastructure spending is the solution (not sure I agree with that one) then federal funding for fast-tracked subway network construction in regional population hubs would be ideal. Massive up-front costs (pouring money in the economy) coupled with long term huge productivity gains. Never happen though, sigh.
