Does taxing the rich cause millionaires to flee?

I'm guessing only if they have some better place to flee to.

And just imagine it populated by millionaires!
hermitcrab•2h ago
Imagine having a billionaire with a fragile ego and the emotional development of a 10 year old, deciding whether you get your weekly supply of oxygen.
atmavatar•2h ago
Wasn't that a big part of the plot of Total Recall?
hermitcrab•1h ago
Yes. In the film the authorities cut off oxygen to people rebelling against their authoritarian rule. Which is very bad. But imagine it happening because you posted something slightly mean on social media.

Very well studied; pretty much the decline of california right now; and city of detroit as examples where this happens.

A great example was Sweden who implemented a "financial transaction tax" of ~2% which was insane. Stockholm exchange dropped well over 60%, about 50% of which moved to London UK. Liquidity in stockholm essentially went to 0, which means no more retirees.

A shocking amount of businesses fled sweden and they had to repeal their own tax because it was essentially crippling their entire country. It was so bad that the government was forced to greatly deregulate the financial markets to attract businesses back. In the end they killed their own stock market and it had to be sold to a private entity. 10 years after their idiotic tax did they even start to see recovery.

Better yet, this recovery was mostly dotcom bubble stocks that eventually popped only years later further setting back stockholm. Recovery was probably about 2005? Luckily they were significantly impacted by the financial crisis.

tldr: a 2% tax on millionaires caused so many to flee that even after repealing, 20 years of damage continued.

>tldr: a 2% tax on millionaires caused so many to flee that even after repealing, 20 years of damage continued.

A 2% financial transaction tax is very different a 2% income tax though, isn't it?

incomingpain•2h ago
>A 2% financial transaction tax is very different a 2% income tax though, isn't it?

The severity of the tax is what makes the story worth telling.

It's important to note as well. When you're talking about "millionaires" it's extremely rare for anyone to be under 40.

The 68 year old retiree is who a millionaire tax hits; but they are specifically the people who are dreaming to move to florida or a tropical island. All of these destinations are actively doing marketing to attract such people to spend their savings in their country.

Florida for example calls it's EB5 visa where you move your money out of sweden and into the usa and you permanently stay in the usa.

>The severity of the tax is what makes the story worth telling.

I wouldn't call an extra 2% tax on income above $1m per year severe.

US taxes have been much higher than they are now:

I suspect a good percentage of the people reading HN fully expect to be millionaires or billionaires one day, so they probably aren't too keen to increase taxes for the super rich.
ThrowawayR2•1h ago
"Millionaires comprise about 8.8% of the American population." according to https://www.forbes.com/sites/jackkelly/2023/05/23/the-making... and that's the general U.S. population. It's probably an order of magnitude higher for HN.

A million dollars of accumulated wealth was a lot of money, when the term was first coined in the 18th century. Nowadays, not so much.

UK is seeing anecdotal evidence that yes, it does cause millionaires to flee. Also gives well-earning non-millionaires the final push.

I'd argue it is less about the tax level and more about value for money. UK services are in a downward spiral while the taxes are going up, which I think is the core issue.

Even if you don't rely on, say, public healthcare as a rich person, it does affect you, as it pushes the equilibrium level for your premium service.

Do you have any actual numbers, or just anecdata? The linked article quotes numbers.

Gary Stevenson of gary's economics argues that the rich are much less mobile than working people. In owning land, assetts, and businesses it's very difficult for them to leave or for their departure to insulate them from taxation. In short, the Rich are very easy to tax and it's hard to them to evade just by changing primary residence. https://www.youtube.com/shorts/Mcf6dbxUVx0
