This is a great thread. This is a matter I constantly think about, and it's great to have input from someone other than my close friends.
Here's the thing: I was born and have lived my whole life in Venezuela, the country that holds the Guinness World Record for the most international beauty pageants won; we're also the country with the second highest rate of plastic surgery per capita (that is, the amount of surgeries performed yearly divided by the country's total population), surpassed only by our southern neighbor Brazil, and we Venezuelans are the people who 'invest' (i.e. spend) the most on cosmetics, beauty products and treatmets in the whole world.
That being said, I was never considered too attractive. Not ugly either, but just average, and in a place like I just described, well, that's not such a good thing. However, in the last two and a half years, since I started College, I began taking swimming seriously and dumped my glasses for contacts so I could finally start my orthodontic treatment because I didn't want to wear glasses and braces at the same time (keep in mind that Colombia, our western neighbor, created "Ugly Betty" around the time I was in 8th grade, and it was a huge hit here too). Now I see a difference. I get way more stares and compliments and people even pay more attention when I talk or, say, ask for something in a groceries store or at the movies or SubWay.
Sometimes I feel bad or even a little hypocritical when I look directly into a beautiful girl's eyes when she talks to me, and then a second later some other girl who's not so, let's say... gracious, approaches me, and I don't, but what can I say? I have been on both sides, and I call tell that there's a big difference, but I think that it goes a bit deeper than our seemingly national superficiality. It's more of a Darwinian evolutionary thing, and it's been going on since the very beginning and probably will never stop, but I admit that it's unfair and sometimes downright sad.
