Is trickle-down strictly about money or about value in general? Because during the last 20 years, just (for example) the access to computing power and information did in fact "trickle-down" to almost everybody on earth in the form of smartphones and Internet. This value was worth a king's ransom in the past. But indeed, the number of TSLA stock in one's pocket did not trickle down from Elon Musk to the rest of us. Not sure why that matters though. In fact, looking in the article, they talk define trickle-down as "cutting taxes on the rich [...] eventually benefiting everyone" then complain about "very high level of income inequality and an extreme level of wealth inequality". You can have both true at the same time.
