Ads suck. That's the conversation I'm going to jump in on. Ads suck. Two reasons why. Let's assume you don't actually buy shit that the ad is selling.
Reason number one. Ads are society's window on you. If you're watching, it's for you. I may have stolen that line, but it's a good one. You remember that shitty ad, where a good-looking guy buys his good-looking wife a lexus for christmas, so they can cart around their good-looking kids? How many people are going to watch that ad and buy a lexus? A couple. Are you? No. "Problem avoided!" Not so fast. The ad didn't sell you a lexus, but it sold you a family. It sold you a haircut and clothes and accessories and a house and "the american dream"; pretty people look like this and they drive a lexus. You're not an idiot so you didn't go out and buy a lexus, but you did look at the pretty people. Your argument was "do pretty people buy lexuses for christmas?" and you accepted "this is what pretty people look like" and that ad didn't sell you a lexus, it sold you Niemen Marcus. Or, considering the forum, it sold you Marshall's. It still sold you something.
Reason number two. Even if it didn't sell you anything, because you're the smartest of the smarts, it still got everyone around you. You maybe didn't even see the ad, you probably didn't even see the ad, but everyone else did and everyone bought "this is what pretty people look like," especially because they've been buying it their whole lives with slight changes in style, and now you have to conform to that. "But I don't shop there." But whoever designs your clothes, unless you sew and tailor your own without ever looking at what anyone else is wearing, is making things in the proper style of today plus or minus five years. Maybe you don't "shop there" but I bet you wore a windbreaker in the 90s and don't today.
That's my mustachian people problems, as the OP put it. I don't watch ads and they still affect me greatly, but I don't know precisely how, and whether I mind or care, and whether it's harmful.
