My perspective...
The realisation that got me interested came a few years ago. I'd been a member of this board for roughly a decade, but had never much poked my nose out of the Philosophy section. Several of my friends are in positions in government, or the military, or various intelligence services, and I started discussing these things with them. I also contacted my MP for the first time, about an issue that I thought was both important and easy to fix (a fairly obscure piece of financial legislation that I'd run into at work.) And at work, I became involved in some aspect of government regulation of the markets.
And something struck me. The people I was dealing with, people I'd always imagined must surely have some solid understanding of how things worked that exceeded my own, didn't really understand what they were doing. The guy whose job it was to create government bonds knew about as much as I did about bonds. They guy working out how to track emissions from transport, basically had to come up with a model from scratch. The MP, a considerably more important person than I had first grasped, knew very little about the legislation I was talking about, despite being prominent member of the committee that had drawn it up not six months previously. The intelligence guy had a somewhat cartoony vision of international politics, as a result of years of being encouraged not to get too engaged in politics, and talking about current events only in the vaguest terms for fear of revealing something he shouldn't. These people are not ignorant, nor are they stupid. But they simply don't have access to a magical source of comprehension that we all lack.
Here on these boards we get a discussion very much like the ones that they have. This board tends to attract people with fairly.. interesting opinions, but then government isn't exactly a neutral apolitical environment. The point is that the world is being run by people listening the same sorts of arguments as we get on some of these threads, and sometimes at roughly the same level of depth and attention to detail. Maybe you can see now why I'm mainly interested in arguments that can be repeated and understood by lots of people? Because those are the ones that will go on to run our world.
A year or so ago I set out to find out who exactly was the final authority on an issue in the UK banking rules that I deal with. They're not well written, being scribed by groups at a European and UK level who not only don't talk to each other, but in some cases are actively opposed in their aims. I traced the through to the people at the various regulatory bodies, who in turn listened to various industry experts in banks and exchanges and financial institutions, who in turn got their opinions from arguments advanced by specialists in their areas, either in house or consultants and contractors. I found out that they are basically coming from someone I knew in Lloyds, an accounting firm that was relying on two guys I knew who often traded arguments with each other, and... me. There are few things more horrifying that trying to work out how the system works, and discovering it's based on an email you sent a few months ago, in a bit of a hurry. Not because I'm some kind of genius, not because I'm particularly important, but because I'm in an area inhabited by accountants and mathematicians, and most of them can't write clear explanations for things. So the industry consensus on how the rules work turns out to be the same guestimate email I sent out a few months ago, spelling mistakes and all.
I'm not the only one. A few years back a group of tin* traders I knew were trying to work out between them some of the basic drivers of the tin market, which went through calm periods, and then frantic periods of trading. In particular, there was one week every year where nothing ever happened. They spent months trying to tie this back to some kind of industry or global event, and eventually decided to all meet and talk about it. They discovered two things. 1) Between them they or their clients held just under 90% of the tin in the world. 2) they all went on holiday in the same week.
These people aren't the 1%. Most of them are probably the 10%. But they're running (a small part of) the world, and they know about as much about global events as we do. In some cases, probably less.
Politics isn't irrelevant. It's a shorthand - broad brush inaccurate statements that allow people to approximate good decisions. And that's what the world is run on.
If that scares you as much as it scared me, then maybe you'll get more interested in politics like I did. I'm presently trying to join a political party, but the local party is run by people who know each other, and meet by common arrangement, so the public listings of their meetings isn't accurate. I literally can't find these people. But I'm pretty sure they won't know any more about politics than you guys do, and probably less. I don't like politics, particularly, but what the heck else can I do?
