And don't get me started on Switzerland. I live there. I'm Swiss. We have massive tax evasion. We have special tax deals for foreign nationals living here.
Here in Zurich, where I live, the cantonal (state) finances are under huge strain because all the wealthy people live across the border in other cantons where the taxes are much lower, but commute into Zurich to work. So Zurich gets to pay for the infrastructure, for the poor who live here rather than across the border, etc.
So please don't talk about some imaginary Switzerland that supports your self-serving rhetoric.
Some usage taxes might work, but unless they specifically target out-of-canton persons, they will just drive more rich people out of Zurich, exacerbating the problem.
At the end of the day having every 20x30 miles plot of your country independently decide on taxation is not be the best idea.
Different tax regimes can only coexist when taxpayers' mobility is limited, otherwise the cheapest tax-land wins.
EDIT: I forgot to mention that standard sales tax is regressive by nature (poor people spend a much higher percent of their income than rich people).
A progressive sales tax not based on purchasers income, but the type of good. For example, luxury goods should be taxed higher and basic staples very low to none. This the wealthy could not avoid tax by simply shifting money around political jurisdictions. This system would encourage transparency, encourage wealth creation as well as thrift in lower and middle income earners.
Also, a side benefit (not that I entirely agree with it) is this is a way to enforce social policy like healthy eating. Tax unhealthy items like sugary food and tobacco highly (up to a point). This is done already in the United States successfully. And if you want more tube riders and less drivers in a city, have a very high toll and vehicle purchase tax. Singapore does this successfully.
Some countries that have no income tax already employ this to an extent by taxing certain sales and imports. I think this type of system is worth experimenting with at least on the city-state or state level (canton / province / state). If it does not work, you can always go back.
There's been talk of this type of system in the US but it's not likely to gain traction. The real reason for progressive income tax is not good policy, but divide and conquer class politics. Something all sides of the political probably spectrum agree with: governments need to be good stewards of tax revenue no matter the collection method.
https://en.wikipedia.org/wiki/FairTax (note the section on prebates for poor people - similar to basic income).
Effectively, a country engaging in such tax procedures would be throwing out rich people, and while I can hear the jeers of "good riddance", I'm afraid that it's not really a good thing for tax revenues.
Except land, which you cannot very easily move from one jurisdiction to another.
Edit: One recent example of the latter comes to my mind, of course. This is the case of properties in Crimea, now annexed by Russia. This is effectively a jurisdiction change. And it has some practical consequences, of course, although maybe not immediately related to tax; Crimean people need to register their properties into the Russian system, because Ukrainian property ownership is not recognized by the new powers-that-be. And registering is not free, and not even cheap, from what I hear.
* Easier tax evasion (first-party reporting, B2B untaxed)
* Discouraging of consumption (encouraging saving, DIY & black markets)
* Income-regressive nature of consumption
That said, some of the upsides are pretty good too. And if we were switching from FairTax to the current system, the latter would seem even more insane.
Savings and DYI are a good thing long term. Maybe not so much for the inflationary consumer based system that the banks and megacorporations benefit from.
The pre-bate, which is similar to a basic income should help offset the regressive nature. In fact, I think it could replace most welfare programs.
Now that you personally find the already uber-rich Zurich city somehow being on the wrong end of tax deal is your own personal issue.
Personal anecdote - my friend is living in Zurich, commuting daily to Zug for work. But that's another story :)
The reason why there is no tax evasion in Switzerland is multi-layered and very complicated, but in short they cut down on loopholes and tax actually rich people too with tax on wealth or or capital gains. In most places you have 50% or so of tax that is paid by medium-rich people, with actually rich getting away with lot less because of capital gain taxes being lower or controls being more lax or stuff like that. The "50% for rich" is mostly cannon fodder for voters, noone is really expecting anyone to pay that much.
That said, you can't explain the swiss system in simple words, without looking into their long and complicated history etc. I suggest you do more research and get your own conclusions :-)
But it's not true its quite common to pay over 50% taxes. For example, here we got 4 tax-discs, where you pay taxes in a disc until a certain amount of money earned(profits). Disc 1: until €19822,- : 36.50% Disc 2: until €33589,- : 42.00% Disc 3: until €57585,- : 42.00% Disc 4: more €57585,- : 52.00%
That means, you have to pay 52% taxes over the amount you've earned more than €57585.
So in order to pay 50% taxes, one has to make about €300.000,- a year, (either income or profit).
It is not really feasible to tax capital gains with a progressive system. You can make a small case for progressive taxes on capital gains by allowing a basic deduction, but the transaction cost of moving the capital gains somewhere else are generally quite small.
(Just for information, I live in a country from where people are leaving as tax refugees to Sweden).
I'd argue Japan is a good example of a larger well functioning country with fair taxation (up to 40% on income above 150k USD).
Do you even understand the simple truth, that most of the times no law is broken in tax optimalizations? Only when it does, it gets highly publitized. Usually, tax systems are full of loopholes and accountants just need to be creative enough (and yes, they are...). Without breaking any specific law, by logic "what is not explicitly forbidden is allowed".
Personally, I do believe in minimal and fair taxation. If you have system where successful people have over 50% tax burden (quite common in progressive tax systems), you can expect many attempts to get away from it. Just human nature. Your textbook phrases won't help much, do they.
Just look at Switzerland itself - most democratic country in the world, one of the richest (and their wealth ain't based on banking secrecy - whole banking industry brings roughly 12% into GDP... tourism and high quality exports are primes here). Low personal and corporate taxation, and the country and system just works. Why cannot rest of europe work this way? How much tax evasion is within Switzerand? Almost none...
