where i live (Seattle) small businesses are trapped in a death spiral as their rents are going up, the wages they have to pay are up to even attract workers who also need to pay rent, but purchasing power has not caught up.
I know LVT is the libertarian dream, but in practice it means only the rich can own real estate long-term, in most cities. It also means the rich can drive out the poor by driving up land values around them, to the point where the taxes are too much to afford.
LVT simply wouldn't be a good system, if applied in the real world.
Anyone who had to move for a job or wanted to downsize their house for retirement years would be screwed, though.
In other words, if selling removes much of your capital, you then don't gave capital to spend on the next place.
Conversely investors become even more motivated not to ever sell. They can defer the LVT forever, and just use the property as collateral for loans (ie getting liquidity without selling.)
And LVT just becomes an expense built into the cost of rent. The investor never pays it anyway, the tenant ultimately pays it.
Two identical properties, one under mortgage and one that isn’t, have identical rental prices. The costs to the landlord are irrelevant.
Treating wage and capital income equivalently would require recognizing losses due to inflation and risk that simply don’t exist in a meaningful way for wage income. Taxing them similarly without very negative consequences requires recognizing these differences in some fashion.
Taxing wealth has myriad additional problems. In the US, about 2/3 of wealth is completely non-liquid so any theoretical valuation is fiction and highly leveraged.
We already assess property each year for purposes of local property taxes. Treating a 10% rise in value as taxable income each year would shake up the real estate market. Speculative gentrification would certainly stop. And those sitting on empty houses would either sell or try to find renters.
The same fear will happen if you just target investors owning multiple real estate with this tax, or simply forbid by law from owning several flats in high demand areas. The right wing would scream that the hard working French guy won't be able to invest his hard won money, but the very rich foreigners from Saudi Arabia or investments funds from USA will find a loophole thanks to their infinite money and buy all the french real estate.
Hell, most people in my country are against inheritance tax despite a huge part of them not rich enough to pay it, meanwhile inequalities are rising because of inherited wealth. So taxing the land won't happen, the bourgeoisie has been too effective in its propaganda.
Most places do tax real estate. I was surprised to look it up and find that Paris has some of the lowest property tax rates in the world.
Land Value Tax would be a little different, though. It's a proposal to replace most or all taxes with a simple tax on the estimated value of the land. One of the key features of LVT is that if land becomes valuable over time, the tax on that land becomes so high that the owner is forced to sell it. The idea is that the LVT ensures optimal usage of the land by forcing people who own land in valuable areas to use it for a business. So if you buy a house and the area becomes popular 10 years later, your tax bill might get so high that you have to sell it to a developer who will build a high-rise on it, or a grocery store that can afford the high tax rate.
It would never be accepted in practice when everyone's 70 year old parents were being forced to sell their modest forever homes. There's also a major problem where the structures aren't considered at all, so one person with a $2 million home living next to someone with a $200,000 100-year old home would pay the same tax rate if they're on the same size lot, because it only cares about the value of the land.
I don't know why Land Value Tax has become the default solution to everything on the internet, because I think most people would actually hate what it did to society. Having progressive taxes that scale with people's income, spending, and size of their home is good for making the tax burden proportional to wealth and consumption. Replacing it all with a tax that just taxes how much your property is worth ignores everything except the value of your land, which is completely out of your control over several decades of life as the world changes around you.
I know this is argued as a reason for high unemployment on the internet, but it does not match my experience in the real world at all. Having a job that pays a little is more income than no job at all. People stuck with low paying jobs often have multiple jobs as a result.
People owned houses and cars by working at grocery stores. A single income from any white collar job supported a stay-at-home spouse. Teenagers bought cars by working part time. College kids paid their tuition and living expenses for the full year by working summers.
That today's below-poverty-line job still leaves someone better off than being completely destitute is beside the point.
You seem to be confused about the point I'm making, which is that low-paying jobs drive people to take on more employment, not less.
