Fluent in finance is just another forum that says it's your fault your poor. They say you don't play the game right and they may be right for a rigged game. But the fact is you shouldn't be required to play a game to get whats your fair share, and fluent in finance just says you didn't invest right and didn't setup your future right to live off the backs of other workers.
The rest is just hyperbolic headlines which drive engagement which is the cancer of any social media platform. No one makes a billion dollars in income as defined by the US tax code, they make a billion dollars in equity which can be used to back loans which is part of the whole issue of obscuring cash flow. Then they can just use this as fodder to call anyone supporting this idiots cause "No one makes a billion dollars a year" when we know they do, it's just accounted differently.
Your computer doesn't "waste" electricity, power usage is on-demand. A PSU generally has 3 "rails"; a 12V (this powers most of the devices), a 5V (for peripherals/USB) and 3.3V (iirc memory modules use this). Modern PSUs are called Switched-mode power supplies that use a Switching voltage regulator which is more efficient than traditional linear regulators.
The efficiency of the PSU/transformer would be what determines if one or the other is more wasteful. Most PSUs (I would argue any PSU of quality) will have a 80 Plus rating that defines how efficiently it can convert power. I am not familiar enough with modern wall chargers to know what their testing at.. I could see the low-end wall chargers using more wasteful designs, but a high quality rapid wall charger is probably close to if not on par with a PC PSU. Hopefully someone with more knowledge of these can weigh in on this.
