I don't know if any other personal finance bloggers have more than twenty years of data, but I haven't seen it posted. Now and then I like to update what the really long-term picture has looked like.
The graph has networth (blue) and the split into retirement accounts (green) and non-retirement (brown). The record starts when I first arrived in the US in 1990. The early years I was a grad student and then a post-doc and visiting assistant professor and in debt. Then I got a better job as a researcher in the late 1990s and savings began to accumulate. Unemployment and a stock market crash lead to a decline in 2002. Then an even better job in the mid 2000's followed by our move to Australia, merger of finances with Snork Maiden and a worse financial crisis saw net worth plummeting from near $500k to less than $200k. Since then the market rebounded and I've had a couple of jobs where we have largely saved my salary and we are now at a new high in US Dollar terms. The path seems a little smoother when measured in Australian Dollars:
I don't know whether this stuff might be useful to people just starting out to give an idea of how things might look in your future. If you don't dramatically expand your standard of living, higher paying jobs in the future can have a big effect on savings (countering the idea of the importance of starting early). And there can be some big deviations along the path. This one charts spending versus total income including market returns:
The big bumps are usually associated with international moves. Now with two of us in expensive Australia, our spending has bumped up to a new plateau but this graph isn't adjusted at all for inflation so the escalation in living costs is not so great, really. This is very roughly the inflation adjusted numbers (2008 US Dollars):
