The one thing that is wrong with the world

The world is evil because it's filled with evil people - but that fact is too vague to be useful.
L. Ron Hubbard said all the problems in the world are caused by Suppressive Persons, who live in a subconscious degraded state. They make things go wrong without knowing why. Hubbard really hated his enemies, who wouldn't do what he wanted them to do.

I myself have dedicated my life to attacking the world's computer programmers, my version of Hubbard's SP's. There is nothing worse than these people. I hate them so much for all the bad things they do I can hardly type these words. They are worse than the vilest scum, worse than the Devil, because programmers really exist.
These people are evil because they knowingly make defective software that JUST WON'T WORK. I have a list miles long, from Windows to browsers to dumbphones. Computer programmers rely on users' dumb conformity not to notice or complain but just try something else and go in circles forever.
System users' willingness to accept evil is what makes the world go round.

One philosopher said that evil is merely the absence of good, and that is also true.
To put it in the simplest possible terms:
EVIL IS THINGS THAT DON'T WORK
