I am always amazed how many excuses and how many arguments are there when big businesses profit at the cost of the average Joe, but God forbid when a mere employee tries to do the same.

I see no reason to be "ethical" anymore when it comes to employment because I know that it will be one sided - in this case I will act purely in my own interest, just like the businesses do. There's zero reason to play the game where the other side gets to change rules at will and forces you to get along with it.
