The problem is that the people (investors) that lost the money in the past, and the people (investors) making it now are DIFFERENT.
The US shale industry lost $300B 10 years ago. A big wave of bankruptcies, assets auctioned off. New companies bought the assets. By and large, the shale sector is supported by investment banks and large holders. So the money is being made by wealthy speculators that got in at the right time.
Ideally, we would like to see that money poured into worker's paychecks. But the consensus is that development (requiring roughnecks) is not surging. The money is going into rich folks pockets.
Ofc, the oil majors are also getting a cash infusion, and they are held by a bunch of retail investors (including me through my index funds) including the proverbial grandma living off XOM dividends. I suppose that is a good thing.
But as the video above suggests, the entire industry is going through a terminal spasm of profiteering before getting devalued. Not because the taps will get turned off and there is no more oil. Just a few years of profiteering before all the oil assets (in the ground) get written down bc the projected total global future usage drops from exponential growth to (slow) exponential decline, and those assets will not get developed in any investor's lifetime.
If you currently own the shale assets and are setting these production/pricing inputs, you are a vampire capitalist. You know your business is going to get written down in the future (like how US coal company market caps got wiped out more than a decade ago, never to recover), so you are going to make as much money as possible with minimal reinvestment, and try to sell out at the right future moment.
And those proverbial grandmas (and us index investors) and taxpayers will get left holding the (debt and toxic waste filled) bag.
