>But aren't tariffs a textbook example of the theory working in reality?
No.
Trickle-down economy fails because the percentage of their income the rich spend on everything shrink further the richer they get.
For example, if Elon would still be spending a quarter of his income on the same type of food items he ate back in his college days, then his spending would actually drive a vast part of the economy, from farmers, to cooks to plumbers. We'd be then using his money to renovate the infrastructure, just so that it could accommodate the enormous, multi-million dumps he takes three times a day. Instead, he spends it on Twitter and on pimping out virtual clone of his exes.
Which is why taxing the rich is good - they literally can't spend the money anyway and tend to start blowing it on dumb, sus and criminal stuff eventually.
