Let me start by saying I don't want this to be a poo-flinging thread or a rehash of old discussions. I've just become inundated with anti-capitalism stuff lately and its been kind of driving me crazy so I wanted to talk to some smart left-minded folks which I am assuming is nearly everyone in this forum.

First, a few questions:

1) Is it morally wrong to pay someone 1 dollar an hour? If yes, why? If no, what is a set of conditions where it becomes wrong to pay someone 1 dollar an hour?

2) I am a gold miner. I spend five million dollars to buy five potential mining sites (at one million dollars per site). I am speculating that one of those sites will have 5.5 million dollars worth of gold thus my expected profit is half a million minus overhead. I spend 200k on mining crews and equipment to speculate these mines, paying each of them 10 dollars an hour. Four of them are dead ends, but luckily the fifth has a gold vein that I sell for 7 million. I have profited 1.8 million dollars. Am I wrong?

3) I am an entrepreneur. I invest one million dollars in a restaurant. I estimate that I will lose this investment about 80% of the time and 20% of the time I will have a successful restaurant that will repay the investment x5 in a few years. Luckily, it is a hugely successful restaurant that nets 1.5 million dollars in the first year. How much should I pay the bus-boy? I paid him the minimum wage. Am I wrong?

4) I was a big fan of Back to the Future 2 so I decided to invent the Hoverboard. My Hoverboard company of which I am the primary share holder nets 500 million dollars a year, which I can spend or recapitalize at my discretion. How much money is it ok for me to take for myself?

5) Is profit wrong? That one is obviously a tongue-in-cheek rhetorical, but seriously, what are some sets of conditions under which profit becomes wrong? How much profit is too much, and why?
