Fructose is pretty bad for your liver, I remember my Organic Chem professor railing against it. There is so much conflicting evidence in food science, it can be VERY difficult to study the longterm effects of the consumption of certain foods. I have a good friend who has her masters in Dietetics, and is a Registered Dietician. She hates how demonized fruits are, and was just telling me how for years RDs have been trying to stop MDs from telling dietetics not to eat fruit. Whole, fresh fruits in moderate quantities are certainly good for you!

And the electronics certification for Aircraft is slow and expensive. I think the dual jack was designed and approved before cell phones and media players were common (let alone allowed to be used)

Also, I would bet there was a level of "tech lock-in" ensuring the only source for the headsets were one or two companies.

The logic is really simple:

You owe income tax on your income. There is no exception saying that illegal activity is tax-free. (The only exceptions have to be written as laws, the IRS doesn't get to decide.)

Therefore, even illegal activity is technically taxable.

It's also pretty easy to see if you made a ton of money you didn't declare on your income tax because if you spend it then it had to come from somewhere.

Before the invention of time zones, each locality decided what time it was by setting "noon" to the time of day when the sun rose to the highest point in the sky. That worked well enough when life moved more slowly.

After the railroads connected cities and it became important to know to the minute when something was scheduled to happen, a difference in "noon" between your town and mine made scheduling extremely difficult. Time zones were established so that people all over a region could agree that 8:00 is 8:00, even if that meant the sun reached the highest point in the sky at 12:04 in my town on the same day it reached the highest point at 11:44 in your town.

An agreement like that works well for people up to a few hundred miles apart. Much farther though, and you'll have to convince people in the far west portion of the continent that the sun rises at 3:00 a.m. on the same day that the people in the east say it rises at 6:00 a.m. So they divided the continent into "time zones", each 15 degrees of longitude wide (which is what you get when you divide the planet's 360° by its 24 hour rotation period) as a compromise between everyone-everywhere-agrees-to-use-the-same-clock and everyone-gets-to-use-whatever-clock-they-choose.

It basically means how much an issue is on people’s minds and how much an issue has on public opinion. As an example, in the 2012 election, health care was a high salience issue since the candidates talked about it a lot. In 2016, immigration had increased salience- it wasn’t talked much about in 2012 but Trump’s nomination and “build the wall” increased the salience. In 2020, immigration was lower salience since Covid and Black Lives Matter took up most of the dialogue.

Edit: I’m not sure if this fits your context. I’ve only ever heard the word with respect to politics.
