Pretty much anything with a value has, was or will be taxed. Or get tax relief. At its essence tax is a percentage of cost/price, and to do that the thing being taxed has to have a value.
Pretty much anything with a value has, was or will be taxed. All that is left, is things without value. By desiring to tax them, if that comes to pass, we need to allocate them a value.
The boldest example is perhaps unpaid childcare. That has value to society and is worthy of a tax credit. But to do so, it needs to be given a value…. Suddenly the unmeasured by GDP niches get to shine.
But I want tax revenue. What do rich people have that hasn’t been allocated a value? Working out that is something that can be done, but is damn hard. Some ideas to get you started:
Valet Parking / First Class Flights -sound good on the surface, but the market has already decided what these things are worth, even if they are unpaid (directly), and even if the won value (separated from the poor) is different to the nominal value (some nice food and wine). The rich won’t pay more, which means the providers receive less. To balance that, they will raise the prices for their less wealthy clients.
So, it can’t be transactional, unless that business purely services the rich.
What do the rich value, but has no transactional value?
Peace and Quiet. I guarantee there is a direct connection between wealth and density of people, regardless of being at home or not. I feel it is clear that we mix with the rest of society, densely, because it is needs based. Rich people choose to be separate.
We can tax that. Assign peace and quiet a value, an allocated value, and charge it according to distance from others relative to population density. We are all going to be tracked one day, so that is perhaps a good use for the tracking.
Just like I get health insurance because it saves me paying an extra Medicare levy, rich people could be persuaded to mix with everyone else a bit more, I’m sure it can’t harm.
