What would would be a more moral system of exchange and why?

A monopoly has the demand schedule p = 210 − 0.2q and the marginal cost schedule MC = 20 + 0.8q (a) If it can practise first-degree price discrimination how much should it sell? (b) If it can practise second-degree price discrimination and it has already made the decision to sell the first 100 units at a price of £190, what price should it charge for the rest of the units it sells?

Bill Gates, even though no longer a CEO of Microsoft, still cares about the profits of his company. Assume it costs Microsoft $1 per copy of a new WindowsXX, and the inverse demand for this revolutionary product takes the form P(Q) = 60 – 5Q. A. Assume the plan to chip people worked out perfectly and Bill Gates knows exactly the willingness to pay of all consumers. What would be the profit of Microsoft then? B. Assume instead that Microsoft is allowed to do block-pricing with 2 blocks. What happens to its profit? C. Finally, assume Microsoft was able to separate it's consumers into business owners with inverse demand P (Q) = 40 – Q - and others with inverse demand P (Q) = 20 – 4Q. What would be Microsoft's profit?
