The start and end dates on those graphs is somewhat arbitrary. If you compare the long one with a graph starting in 2000 and ending now it's going to look vary similar. But as they say past performance is no indicator of future performance.

If because of the credit crunch people pay down their debts then we are going to look at a few boom years but that's going to take a while.

That graph is rather confusing. The lines are all grey initially with no easy way to follow them without trying to hover on the one you want. Then the interpretation also becomes a hassle. Ugh.

BTW: they don't seem to use reinvested dividends - though this wouldn't change the underlying trend much.

a good effort at the chart, although comparisons are still a but tough..
