This is a perfect example of why taxing income is not the correct way. Things like progressive sales tax and taxing usage is. For example, those commuters should be taxed enough to support their burden each time they come in to the city. And for those companies within the city limits enjoying the infrastructure, protection of law, etc, a sales tax on their products sold should cover that. The point of tax extraction…
What should the sales tax be progressive on? You don't know the buyer's income when they pay for stuff. 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 c…
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.
