Laffer Curve Explained: Why Tax Hikes Can KILL Revenue! #shorts

[00:00:00]The year is 1974.

[00:00:02]America is mired in stagflation. Fuel cues snake around city blocks and President Gerald Ford is itching to raise taxes to fix the ailing economy.

[00:00:12]Sitting in a quiet Washington DC restaurant, a young University of Chicago economist named Arthur Laugher is trying to explain to the White House deputy chief of staff Dick Cheney why raising taxes right now is a terrible idea. To make his point, Lafer grabs a napkin and draws a crude curve. This animated diagram recreates his logic, plotting the tax rate against government revenue. Laugher's first premise is obvious. If the government taxes the population at 0%, it collects exactly 0 in revenue. But then he explains the opposite extreme. If the state taxes people at 100%, why would anyone bother going to work or opening a business?

[00:00:53]economic activity collapses and the government again collects zero revenue.

[00:00:58]Somewhere between those two zeros lies a magic point. A tax rate high enough to fund the government generously but low enough that people still want to work, invest, and hire. That sweet spot is the peak of the curve. The idea is simple.

[00:01:13]The problem is that the peak is invisible. You only know you've crossed it when you start taxing more aggressively and collecting less in return. Right now, modern Britain is running a massive unintentional experiment to find out exactly where that peak sits. To balance the books, the chancellor recently delivered what amounts to an everything everywhere all at once tax rise, hiking rates and squeezing thresholds across multiple sectors of the economy. Take capital gains tax. The government slashed the annual tax-free allowance from 12,300 down to just 3,000 and raised the rates.

[00:01:50]The logical expectation in the Treasury was that by casting a wider net, they would catch more revenue. This chart tracks UK capital gains tax receipts and the early data shows the exact opposite happened. Despite aggressive hikes, revenue plummeted from nearly 17 billion in 2022 to under 14 billion, a drop of over 20% in 3 years. The math failed because it treated taxpayers as static targets. Investors with the option to sit on their gains are doing exactly that. They are holding on to their business assets longer and deferring their sales to avoid the new steeper bite. Policymakers increased the effective tax burden and as a direct result the revenue went backward. It is the laugher curve functioning in reverse.
