I have had this sneaking suspicion for years now that most of the money needs to be locked up because if we actually gave it to the masses to spend we'd see massive inflation and/or environmental catastrophe (worse than the current one). I don't mean to defend the wealth gap, and I'm not trying to make a statement on how things should be. I just think there may be an unfortunate reality that we need most of the world to have less because we can't currently support a middle class globe.

A land value tax would fix rich people parking money in real estate. A wealth tax or capital gains tax would not.

Is there a country that has implemented these ideas and where the results have been like you expected?

Income from capital has a low tax rate in the US (and many other countries) because you can deduct neither losses due to inflation nor losses due to risk, both of which are substantial for capital income but non-existent for wage income. The lower tax rate is simpler than actually accounting for these differences.

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.

Is capital gains / wealth tax a fix here though? Definitely not saying it doesn't work, I have no idea. But I'd be curious to hear both sides of the argument.

> You bring down price of home land rent then price of everything else comes down

If any price for any reason goes down, that money ends up in housing. The only way to bring down housing pricing is to build more housing. This is extremely well documented.

Or you tax it. Or, more correctly, you remove the current protections that allow land to appreciate tax-free for decades. That would move capital out of land and free it for other uses. The current system was designed to put money/people into houses post WWII but has gone too far in promoting radical multi-generational wealth structures.

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.

I agree, but taxing real estate as an investment would break the wealth structure of many voters (and politicians) above the 80th percentile of wealth. For half a century, in France, it's been told that real estate was the safest/best investment for households; everyone was passively peer pressured each year, whatever the macroeconomic situation at the moment, to buy. This is a Ponzi scheme, so even the middle class households that recently bought their own shitty flat in Paris will never vote for such a tax because their overpriced asset would lose value and it's often their only lifelong investment.

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.
