So, lets expand that idea a bit. Why doesn't the government just buy a lot of shares in index funds, kind of like an endowment, and then never collect any taxes? I can see a world where a large portion of private enterprise is held/managed by the government, and the proceeds of that is used to fund public works.
Well, the first reason is that most state governments[0] do not have anywhere near enough money in their accounts to get a return that will replace the revenue stream they get today through taxes. You might be able to build it over time by reinvesting budget surpluses.
The other problem I foresee is that the market is fickle. The S&P 500 reached a level in the second half of 2000 that it would not see again for over 14 years[1]. Any investment that needs to generate consistent revenue isn't going to have nearly the growth rate over the long haul that an index fund would provide. That makes the initial investment requirement significantly larger.
But otherwise, I am okay with the government owning a lot of private enterprise via index funds, so long as it has exactly the same voting power that I have. Which is to say, none.
[0] In case anyone needed the clarification, this whole discussion is about state governments; it does not really apply to the federal government for obvious reasons.
[1] Adjusted for inflation. The index did recover to the same number in 2007 just before dropping 50% in 2008.
Well, for the sake of
argument, let’s say the federal government prints all of the money the state would need for an endowment and hands it to the state. There is inflation, but the state never has to collect taxes again.
I think there are some small optimizations we can make to this flow though, like what if the feds who printed the money held the endowment for the state and just distributed payments, instead of letting each state manage its own endowment.
There is a principle of governance that "you are taxing too much" is soo easy to build a platform off of that you will be DOA in elections if you manage any government that tries to invest like you say.
Investment restricted to "government responsibility foresight" infrastructure gets enough flac already. It only takes one down turn for the "golden goose" of the investment to be spent on the buddies of who just got into office
