If businesses expects consumer spending to pick up sharply, maybe they'd invest more - but few business owners expect a sharp pickup.
There might be a boost in capital spending because of a replacement cycle, but with all the slack in the economy (capacity utilization is near record lows and almost double digit unemployment), I definitely don't expect business spending to lead the recovery (as Mussa suggested).
