Extraction is a weird way to put it. Usually, immigrants, especially skilled workers, are overwhelmingly net contributors. That's part of why modern economies want them so badly.
It's actually the perfect opposite, a skilled worker who plans to leave is a burden on their home country as they presumably will use services there they never paid for. Hopefully, in developed nations this balances out more or less. In undeveloped nations there's not much of a system to take advantage of.
I live in a country I was not born in, I pay taxes as much as anyone else and pay into social security programs I'll likely never get to use. The state did not have to spend a penny to educate me. If I return to my home country without having worked there another day in my life, I'm probably quite the net loss to them.
The extraction phase of your life is overwhelmingly being a child or elderly.
On a similar note, Firefox doesn't support <input type="month">, which I was surprised to see (chrome landed it in 2012). I checked their issue tracker and... as you describe. Browsers are complex, of course, but they do stand out as a really glacial corner of the software world.
While I agree a lot of information is conferred, most of it is not useful.
I'm quite a fan of not attending meetings where I don't get specifically invited (as in, directly, not as part of a group). This may or may not fly at a given organisation. Anyhow, my main learning has been that:
1. All truly important information will be repeated (in the form of tickets, slack messages, further meetings). Usually several times.
2. Most useful subordinate information (the kind that doesn't get repeated) only needs to be related to 1 person 80%+ of the time. It's vanishingly rare 3 or more people need some information that isn't ever repeated elsewhere.
The only really useful work in meetings is making decisions. This is an essential feature, but a big problem is often many "spectators" are invited (attendees without decision power or context). Being a pure spectator in a meeting is almost always completely pointless. Also, people like to make decisions/input so meetings are rife with bike shedding (most people have decision power + context for low importance items usually).
You can go to any number of sites (here's a nice one https://webencrypt.org/openpgpjs/), and encrypt a message. You can exchange public keys over any text channel. You can then send encrypted messages over that text channel. Anyone who really needs to send encrypted messages, trivially can. Of course, many criminals won't, but should we all sacrifice our privacy for such a pathetic measure of security?
