Socialism and communism are different things. Socialism isn't just "everyone has the same life and everything is owned by the state." And idk about you but I'm going into the field of genetics because I want to learn and I want to make a difference, not because I want to make money. If I cared more about money, I would be staying at my job and working my way upward, but instead I'm focusing on schooling, which is expensive and putting me in debt. Tell me again how the ability to go to school full time without having to work at an amusement park for minimum wage simply to survive would make me not want to pursue an education and career in my field?
Not everyone only cares about money. So if it weren't for capitalism, people like you could play on itch.io all day and people like me could actually achieve something without starving in the process. Just because your dreams revolve around money doesn't mean no one will ever do anything without money as a motivation.
you're right to an extent, they are not the same system. But they are rooted in the same philosophy. So called democratic socialism is dangerously close in its language to Marxist philosophy. When is it ok to take an individuals assets for the, "good of the people" or when is it ok to silence a persons beliefs due to it being considered, "dangerous or destructive" to a society. That is where Democratic socialism, and what would result from its implementation, are far to close to the systems of the past.
