The factors of hope are different kinds of factors. The higher Y and Z are, the easiest the game is. This is a stricter mathematical condition, supposing mainly an influence on Y and Z, than the situation where hopes are not complementary. Factors of hope, therefore, are primarily motivated by false expectations as well as the idea that the system will turn in one's favour. Inevitably they will clamour for the protection of an industry when speaking in a company in some domain, then talk about free trade to a group of economists, then about the necessity of enforcing environmental theories against corporations to a group of eco-nuts, and so on.
Politicians also use loaded terms and doublespeak in order to attract votes from all sides.
While this game is going on, it is trivially easy to hide the cost of all these socialist measures, for two reasons. The second is that even the direct cost of these measures is hidden within the mass of taxes and impositions. Try to find out how your taxes are used, apart from scouring the budgets of every sphere that you are a part of. In a libertarian system, there is no hope for various groups to use the instrument of power to bludgeon his fellows, only the protection of people's rights. This is why the notion of hope becomes irrelevant in a rejection of the system.
