It's pretty relevant. Dalio is completely right about trends, even though he does not identify the reasons that the haves and have-nots get so divided (statist redistribution schemes, fallacy, irresponsibility). He is ignorant of Austrian economics, but he still groks much of the essential factors of empires' rise and decline, presenting them in a nice intuitive package that covers things in a way other people just don't. It was very eye opening for me, and it began my quest for an assortment of things better than stocks to preserve my wealth and safety, which eventually was part of what convinced me to put the vast majority of my wealth into bitcoin. The other part being me actually studying bitcoin and economics extensively and seeing all the flaws in the traditional financial system.
