After reading your comparision of 2007-2011 economic conditions I believe you should open this comparision up to your readers, you may get some really funny ones. I would like to suggest one:
2007-You scan the Sunday circular looking for an ATV, mini motorcycle or mini scooter for your boy.
2011-You push a go-cart that you and your son fashioned from parts found in the town dump down the hill.

Small TV found on curb won't work because all TV transmissions have gone digital, and the old receivers can't handle them without a converter box.

Download of songs from iTunes won't work -- massive piracy will cause all for-pay services to collapse.

Windows98 PC useless, since you can't connect it to the internet without immediately picking up a virus.

Social Security check not "huge", since government attempts to bail out the economy have devalued the dollar.

Not sharing one DVD amoung family -- bootleg DVD's are nearly free.

WebMD not in library -- government funding for nonessentials has evaporated. Instead, use pirated DVD.

Last home computer you bought was not sold -- it was nearly worthless. Still works fine though, except for the virus-ridden software.

The TV from the curb won’t work in 2011 as all analog broadcasts will be discontinued. So, no TV at all.... Maybe people will find books from the trash, or the free bin from the second hand book place, to read instead.

from an MSN story: "Legislation passed by the Senate on Wednesday would require broadcasters to end their traditional analog transmissions by Feb. 17, 2009, and send their signals digitally. Such technology promises super-sharp pictures and better sound."

You forgot to put 1967 with the same items as 2011 as a third column. the only TV I watched when I was a kid was rocky bulwinkle on our next door neighbor's TV before school. Then we got a TV around '67 or '68 because we watched batman, disney etc on a 9" black-and-white zenith TV that still works.

Here's one of mine on the 2007-2011 theme

2007: Fly to far off cities to visit your parents and siblings.
2011: Walk to the basement or garage for a visit.

My feeling is that things will be getting much more local and when times get tough people will pull back and try to form traditional extended family groups. If this is the case think what that will do to the real estate market. In 2006 (in the above example) three houses are required, in 2011 only one is required. Consider the numbers if this trend becomes commonplace. A practically instantaneous fifty percent drop in demand for housing if just one formerly independent family component coalesces around another with a job or salvagable house/mortgage. This effect is the accelerated opposite of the familial diaspora in evidence since the 50's. The fact that many families are estranged will doubtless complicate this. However, I believe that the families that do manage to gather in will be much happier than before.

We’ll have government programs to ensure people get their daily intake of Starbucks coffee.

Right up until the whole edifice collapses on itself. (which is probably further away than 2011, although you never know)

Everyone is protected against their bad decisions. Those of us with little debt, lots of savings, etc, we’ll be taxed as hoarders or something similar.
