Stimulus Package

So according to a CNN article, here is what is in the stimulus package:
$142 billion for education,
$111 billion for health care,
$90 billion for infrastructure,
$72 billion for aid and benefits,
$54 billion for energy,
$16 billion for science and technology and
$13 billion for housing.

This just doesn't seem right. Housing is what started all this mess--people who have houses they can't afford and now aren't worth what they paid. So why is housing the SMALLEST part of the stimulus package?

Education is important, but it surprises me that it is the highest on the list. I was under the impression that this was going to be an infrastructure-based package.
