As long as we‘re in a capitalist market, which we are and probably will be for a while, any for-profit company, however small or big it is or however private or public it is, is a capitalist company. You have to be in order to make profit. At all. And yes, usually, the bigger they are, the worse they are. But not every for-profit company is evil, thus not every capitalist company is evil.

And businesses do have a conscience. It’s the sum of their owners‘ consciences.

And also, you do not need to be evil to be successful although it is probably easier.
