This is demonstrably false, at least in American politics. The inter-generational transmission of wealth and power had a half life of, at my last reading, about 1.5 generations.
In Sweden, for instance, about 70% of information gets lost in each generation [1]. After a couple generations, the effect tends to disappear.
Expecting power dynamics to shift every 5 years is silly. People build life-long relationships. And someone good at leading when 35 is probably still good at 45.
This sounded very interesting, so I looked it up. It seems that Sweden during that time seems to have had a 30-70% inheritance tax, depending on the year. That accounts for a loss of 70% of wealth pretty neatly.
It's also the reason why there is much power in money (in Western societies) - the other venues of power (such as hereditary privilege or religion or mercenaries) have been closed.

If you mean the public faces of politics (or the "who is who" in CEOs and such), sure. But you don't mean that ultra rich upper class families lose their power in 1.5 generations?
Interesting to see those stats, but you also see the same family names in politics over and over again (Bush, Clinton, Kennedy...). I could grant that information loss for the population as a whole, and still also recognize that dynasties exist at extremes (Rothschild?).
All the "regular people" could be in a flux of wealth gain and loss, and the true upper crust could also be very good at holding on to power. Your link doesn't demonstrate the falsity of this hypothesis.
The Bush and Kennedy families are currently four-generation political dynasties, while Clinton is a single generation. That'd be a very low upper limit compared to most of history if it does turn out to be an upper limit, but of course there's no way for us to know now if the current generation will also be the final one.
You need to add the influence those families play in local (e.g. state and city) politics, how they intermarry and extend their reach, how extended family (e.g. different-surname cousins) hold political roles and help each other out into power, and so on.
Even going strictly for families:
(...) "my research has thus far identified 167 families with members elected to public office for at least three consecutive generations. Twenty-two families have had at least four consecutive generations elected to public office, while four families – Bachhuber/Doyle, Cocke, Lee and Washburn – have had at least five generations."
Thanks for this and the other links. Does make me wonder whether nepotism or brand recognition plays the bigger role. The more things are accounted for by the latter, the more I want to chalk this up to democracies getting the leaders they deserve, no more.
It just gives it a new public facade every 4-5 years. Those in power remain the same...
