The "make the world a better place" is a jab that got popularized by the show Silicon Valley. They poked fun about how every startup claims they're making the world a better place, and it didn't matter what they actually did. A food delivery service would claim it. Some B2B SaaS would claim it.

And it's all a bunch of baloney. Unless you're solving a problem that threatens the world (climate change, disease, healthcare, hunger, poverty, homelessness, etc.), then "make the world a better place" is eye-roll worthy.
