The oil industry moves unthinkable amounts of money in the world which goes directly to the pockets of the establishment's members who rule their local societies on the backgrounds. That is the reason why electric cars and similar technologies are never fully implemented or opened to everyone for an affordable price.
Oil was indeed black gold many years, but it shouldn't remain like this anymore, because it's already possible to replace it, if there was legit interest from governments, businessmen and bureaucrats.
However, modern slavery is more profitable for them, as renewable sources of energy turn people less dependent, just like bitcoin and financial system correlation, so oil will last as black gold for a long time yet.
Oil prices are not what it used to be, it dropped significantly during last year's pandemic crash, and it never really fully recovered, it is going to be less and less wanted in the future. It doesn't matter how much money they make, which is less around now compared to back in the day, it is all about how many people prefer it. As long as people keep improving the renewable energy platforms, get more energy from solar panels, drop the capital required to build it and so forth, that R&D will come back and result with people using renewable energy.
At the end of the day which one would you prefer, keep paying for oil, or would you rather have something that you pay a lot at first but then free forever? Look at Tesla cars, you wait 30 minutes to recharge it, but then it is free of charge give or take, maybe few cents, whereas cars that run on oil may fill it up in a minute but it costs how many dollars? Eventually people will realize the difference.
