I rreally dislike how big corp figured out that the can sell stuff to each other without actually moving some good. Looking at you, Nvidia... I have a feeling that the ordinary people will again pay for that.
It all was many years ago after the great depression, and similar. Then people kept voting in republicans who's life mission is to gut the SEC and all related regulation keeping them from doing things like this.
The problem described isn't companies buying goods and services. It's buying from an entity they partially own and then profiting as that entity becomes more valuable because of the purchase.
If the parent comment is true, it seems the problematic aspect is the leverage created by the P/E ratio more than the percentage of ownership. What a weird situation.
Yes, if it's done with an intent to defraud the general population, which could be the case here. Effects and intent really matter when deciding actions.
Except the regulators first outlawed what is generally considered to have caused the great depression (savings banks allowed to invest, which translates to very, very rich people being allowed to take massive risks with poor people's money) ... then re-legalized it.
So not only are the regulators not going to allow things that cause another great depression, they're allowing the things that caused the first great depression too. They must want a rerun.
(Because if you don't allow this you're effectively demanding the extremely rich make good investments to stay rich ... and not even France, otherwise pretty socialist, dares to go that far)
I mean, we all understand that this is some sort of circular financial play, but at the end of the day Google is paying SpaceX $1 billion for compute. This is no different from AWS or Azure.
