Games bring you dopamine and makes you addicted. You do not need to physically do anything but type in your keyboard and sit in front of your computer all day.
There's that word again, even if it's appropriate in the context of video games, it's still way overused.
Is this even a real question, OP? Video games are programmed to be easy to level up in the beginning and much harder as the game progresses. Life is not a video game, though sometimes I wish it were--preferably one of the fun ones where you get infinite lives and such, you know?
Probably the best answer I can think of is that human beings are all playing the same game, competing for the same resources, etc. On top of that, humans don't act like your typical video game opponents. The deck is stacked against most people right from the start, and there are more super bosses around each corner than the hardest game you could imagine.
Ugh. What a world.
