[The gas tax] is already understood as a tax on the poor

That is actually false.

Does the facial recognition "system" include the people who entered incorrect data?

making ethanol required far more energy than 'making' oil.

"If you wish to make a gallon of petroleum from scratch, you must first evolve the dinosaur." --not Carl Sagan

So do you have proof or are you just speculating? Because quite a lot of ancient energy went into making oil.

Germany spent 500+ billion euros and failed.

They didn't fail because they're not done yet.

They deep decarbonized their grid decades ago with nuclear.

No, they still buy electricity from Germany every year, mostly in the winter months.

The problem is that the police communicate things like people's home addresses over the radio.

The problem they had was in order to eliminate junk and spam they prevented duplicate questions.

And they did it tersely and rudely.

Stack Overflow tried to be a store of knowledge more than a discussion forum, and that directly or indirectly motivated the moderators to quickly close duplicate questions. I preferred to keep every question open for at least 24 hours to give the asker time to clarify their question and the answerers time to provide a personalized response that answered the question, even when the question truly was a duplicate of a previous one.

And yes, answers became obsolete as technology evolved, so even just being a store of knowledge was elusive from the start. An answerer could later revise their answer but that usually wouldn't reward them with the "accepted answer" so there was little motivation to do it.

If the gas tax isn't regressive, then why would this be?

Like it or not, a High School Diploma is supposed to connote a level of ability.

Yes, that's why grade inflation is such a problem.

Does a passing grade of 21 percent equate to a person who will do all those things competently?

That 21% represents a D-. By way of comparison, the average SAT score in 2024 was 1024 out of 1600. That's 64% which is a D, so a D- isn't so bad..

Smart inverters.

No, it's only saying that Guyana is not a net importer of any of the 7 specified food groups. For example, the USA and Canada are net importers of fruits, vegetables, and fish, and are self-sufficient in dairy, meat, legumes/nut/seeds, and starchy staples.

if you need to make 42 cents, you do a quarter (leaving 17 cents), then a dime, (leaving 7 cents), then a nickel and then two pennies.

That's 5 coins. In Europe, it's only 3 coins: 20c + 20c + 2c.

The problem is, consider getting rid of the nickel. Now try to make 30 cents. You pull a quarter, leaving 5 cents, oh shit you made a mistake. Back up, you should have done three dimes.

In Europe, it's 2 coins: 20c + 10c.

The BIG problem is overspending by the Federal government.

Did a company ever make more sales by cutting costs?

Did a restaurant ever bring in more customers by reducing portion sizes?

If DOGE really wanted to cut costs, they could start by auditing themselves!

Or maybe the problem isn't overspending but undertaxing. As any business knows, sometimes you have no path to profitability except by raising prices.

You're describing a Virtual Power Plant where the utility pays you maybe $1 per kWh during times of high demand.

Or momentary switches on the landing legs.

A professor, or any educator, doesn't need to practice the material. They can beg, borrow, or steal the lesson plan and course work and present it to the students and still be an effective educator.

Similarly, a student has the right to demand a refund from an ineffective educator, such as one whose own competence comes into doubt by using AI to create their coursework.
