Because you're intentionally ignoring the fact that every time you buy a game you're paying more than you really need to, therefore you're keeping less of your wealth than you should.
What exactly is your point? The comment you linked to has me saying I am poor, and the comment your replying to says the same thing. Ten bucks for one full video game in six months is not being overcharged. A pair of jeans is more than ten bucks.
If you're arguing that the only good game is a free game, I'm not going to agree with you. I will happily pirate "AAA" games, but indie games I'll pay for.
Highschool freshman edge bs is annoying as hell. You're not as smart as you think you are.
It is being overcharged when they game should be 7$ instead.
That applies everywhere. You pay 100$ to do your grocery, 30$ goes to the store owner, you're here defending the store owner while you're trying to choose between eating and paying rent.
