I don't know if you can say that Uber has made the world a worse place. That requires at least a total ordering on Uber's biggest actions and probably quantification of the consequences.

If the advent of Uber has resulted in a billion drink deaths not happening but one person making $2 less per hour, it's clear. The other way around is clear too. But as it is right now, you can't assert that as is. You have to bring something more convincing to the table.
