to quote Taleb: those who can, do (trade). those who can't, write about it (financial press)
Taleb is literally mostly an influencer who once traded (and sucked at it).
The quote originated with George Bernard Shaw back in 1903, not Nassim Taleb. And it has always been a lazy take. Some people just prefer to write (or teach).
I like to say, traders and people you put money on the line are often far more honest about economic policy, than economic influencers like The Economist.
