Can someone explain what Supply Side Economics and “Trickle Down” are, and why they are seemingly rejected so much?
Those are political slogans, not economics, despite “economics” in the name. Trickle down specifically was a pejorative used to criticize reducing tax burdens on corporations and wealthy investors. Supply side isn’t a clear set of policies, but presumably they are policies that target aggregate supply (production capability) of the economy but again is largely a political term for policy to directly benefit businesses (suppliers).

Is there a big difference between supply-side and trickle-down economics?
I believe trickle-down is a more specific set of policies within the larger realm of "supply-side economics". While supply-side fiscal policies focus generally on increasing aggregate supply, the trickle-down approach argues that this is better achieved by focusing on policies that favour the upper class and large corporations. For example, a "supply-sider" can advocate lowering taxes in a progressive manner, taxing everybody less but the poor even lesser. While the trickle-down approach would preffer lowering taxes in a regressive manner. More on reddit.com

ELI5: What is supply-side economics and why is there such opposition to it?
Ultimately, a lot of these explanations are just plain wrong, and based on what politicians want you to think supply side economics is. This explanation is not going to be particularly ELI5 (I'll try) but will be accurate, unlike the wrong/misleading answers posted before. Supply side economics is making people make more stuff by making it easier for them to make stuff. This includes: Investment in education Good, available healthcare Large public sector investment in infrastructure Subsidised natural monopolies to bring prices down to marginal cost Minimising disruptive taxes Government regulation when necessary to create competitive markets Politicians generally when they mean supply side policies really mean cutting taxes and regulation. Worse, they normally mean cutting regulation to reduce competitiveness (which is an anti-supply side policy) and reducing taxes such as corporation tax, a tax which has almost no affect on economic activity (which means it isn't a supply side measure). TL;DR: No economist is against supply side measures. Actual supply side measures are either a) already being done, b) politically unpopular, or c) uncertain in their effect. Meanwhile, politicians lie through their teeths about economics. Source: Actual economics degree. More on reddit.com

In other words, he said tax cuts would pay for themselves. The magical thinking sold to the American people was that giving tax cuts to the rich would improve the lives of the majority. Laffer’s theory provided a foundation for supply-side economics and was illustrated by the Laffer Curve, which he famously drew on a paper napkin for then-White House Chief of Staff Dick Cheney in the 1970s.

r/AskEconomics on Reddit: Can someone explain what Supply Side Economics and “Trickle Down” are, and why they are seemingly rejected so much?
November 5, 2024 -

I have a basic understanding of what they are. Essentially increasing supply (which usually comes from investments from the wealthy) is the best way to economically grow, and that supply “trickles down”.

Now when I hear people say “trickle down economics doesn’t work”, they usually cite studies that say tax cuts for the rich don’t work. But I would imagine that’s because the tax rates for rich people are already low enough that lowering them more doesn’t have a great benefit. I would imagine if the tax rate for rich people were like a 99% wealth tax tax cuts for the rich would be good.

Aren’t these black and white statements really misleading? Yes trickle down economics doesn’t work but that’s because we already have made it so that more tax cuts don’t trickle down as much. And the neoliberalism in the 80s seemed to have helped a lot from stagnation. Isn’t their a balance between supply side and demand side economics rather than saying one is categorically true
