i would be slightly more targeted- abolish tax incentives for investment in real estate. investment in real estate is literally rent-seeking, unproductive and is widening inequality , particularly between young and old.
Then real estate is not "rent-seeking".
Real estate owners take the burden of home ownership off the shoulders of renters. Renteres choose to rent because they have an economic incentive to do so. Instead of a buying a home cash, or putting down a deposit, a renter can use that money for investing in other activities, spending on themselves or their family, or save. Of course, there are many renters who cannot afford a down payment at all. For them, the landlord is playing an even more important role by letting them rent in areas where purchasing would be impossible.
I do agree that most tax incentives for investing should be abolished. But I disagree that real estate is less productive than other types of investing.
I am sure there are more.
You might be thinking about 1031 exchanges of business assets (including rental properties). IMO, that serves a generally beneficial purpose as compared to the others that you mention.
