Some people have legitiment business interests in tax-haven type countries that are not about avoiding taxes. No country is just purely a tax haven with no other ecconomic activity after all.
In theory a blanket ban on crypto could harm innovation. This was much easier to believe at the beggining of the hype cycle when it seemed like someone might actually do something useful with blockchain tech. Kind of hard to believe at this stage.
I feel like inheritence tax is kind of pointless by itself. Most people dont just suddenly die and have time to distribute their assets pre-death.
Limiting housing investment might make cost of living go up. Its not like houses just appear out of nowhere. lots of people cant afford to just buy/build a house. Rich people buying houses and renting them out helps fill that gap. It doesn't always work out as ideally at that, but the other extreme of severely restricting real estate ownership would probably screw over poor people too who do not have sufficient resources to get a mortgage. They still need somewhere to live.
I dont really know what independent auditors means precisely. IRS/CRA/etc are already pretty independent. They could be better funded though.
If any single country will try this alone - devastating. For the country :) . If USA alone will try it - maybe it will work, idk. If USA plus EU plus major Asian economies will do it collectively - it will work.
For independent financial auditor - none that I can think of.
For offshore restrictions - you as a country lose all existing assets already there. A lot of people will move their business to a better countries, providing less restrictions and eventually taxes for them. Probably election loss and further dismantling of all these laws by disgrunted businessmen using their pocket political forces. If will hugely depend on the collective size of economies doing the ban.
For housing - its tourists plus rent seekers vs. regular citizens. You hurt one group and you benefit another and vice versa. There is no win win scenario here, balance must be found. I personally vote for regular citizens, even if tourism industry will be hurt a little bit.
I think inheritance tax has huge downsides. Past a certain age, if you've done reasonably well, and are thus most likely to make a huge impact for the better in your latter working years, why do that most useful useful work if you can't pass it on?
We can do it incrementally, so that majority op population is not affected much. And if a billionaire is discouraged from earning additional billions and retire - well, that was the point? He stops working (hypothetically) but his place will be immediately replaced by less wealthy successor (or by more wealthy opponent, but that problem need be analyzed separately). His kids won't become billionaires, but will be a mere millionaires, requiring them to contribute if they want to keep up expenses. All in all I think it is possible to set up such inheritance taxes so that majority will have positive result.
If you're thinking about billionaires, I think you're doing it wrong. Billionaires don't have billions in the bank. They generally have shares in companies which need to be sold to get money out. And the price changes the more you sell. Billionaire "net worth"s are almost useless because they assume each share they sell is worth the same as the last share traded, which would not be the case if they were all dumped on the market, and even less so if the government made a habit of seizing your shares when you die.
Perhaps - I would think in many cases, an equilibrium would be reached. Comparatively few people in any industry are wholly irreplaceable. Still, should something like this just pop into law tomorrow, one could expect a large group of experienced specialists at the top of a wide array of fields to decide to retire, to disasterous effect. Given time to settle in though, I'd wager it likely that talent would filter up to replace any losses at an equivalent rate.
Ultimately, people as a whole like to work. They dislike working under poor conditions or doing jobs that don't feel rewarding. A law like this would generate a lot of change, but I just don't see that change being disasterous given sufficient adjustment time.
Talent won't filter up. You can't replace doctors with 40 years' experience with doctors with 30 years' experience (and keep going - who do you replace them with?) without losing a huge amount of value.
We have that today. For some people it's not worth working, and they might as well retire and stop contributing. As we raise the inheritance tax rate, that number will drastically increase, and we get to raid some one-off money in exchange for much less productive work.
