That is economics 101. But if you had stayed for the later classes you would have had to unlearn that. It is not true.
Maybe that is because "competitive markets do not exist" as the libertarians say, but whatever, in the world in which we live the top automaters are going to make super profits.
What will the world look like when the means of production belong to a small group? In a society (capitalist) where ownership implies control?

Yes ideal competition is just an ideal. But given the right regulatory environment you can very extremely closely mimic that ideal. Maybe even surpass it in terms of encouraging competition.
Implying that I haven't is needlessly rude, and not providing an explanation is unhelpful. Please do better.
"In an econ 101 competitive market you also will not make accounting profits."
The way I learned it, if market participants are making less than they could elsewhere then some will leave. This lowers production and raises the price. This dynamic will raise the profits the remaining producers make until they're making as much (accounting) profit as they could at the next best opportunity, which leaves the economic profit zero. I don't see what drives the accounting profits everywhere to zero.
Zero when accounting for the time value of money. I've read (for instance here http://catalog.flatworldknowledge.com/bookhub/21?e=rittenber...) that firms can make accounting profit in the long run. But they don't go into the requirements for this to happen.... =( But I believe it is due to the time value of money - which, given a long term growing economy with relatively little inflation, will be be long term positive. I'm not for sure though.
It's possible, but - again presuming there is positive opportunity cost - as soon as the economic profit falls below zero it is a better idea for them to leave the industry than to lower their profit further.
I don't undercut your prices because I think I'll be taking home less money. I undercut your prices because I think I'll capture your business and make more money overall. If that leaves you (or some other participant) without the ability to make sufficient profit to stick around, you won't.
*In markets ones with at least some competition
Also, its important to note that even the machine owners wont make profits in a competitive market.
