I do not think utilitarianism does say this. It says that if slavery prevents you from starving, it is
less morally bad. Earlier I used the analogue of high and low. Consider a very deep canyon. Deep in the canyon is a small hill. Looking down from outside the canyon, one might think: "We cannot say that, because the top of the hill is above the floor of the canyon, that the top of the hill is high". But clearly the top of the hill is more high, or less low, than the floor of the canyon. We can say this without saying whether the top of the hill is high or low. Similarly, we can say that slavery is morally more good, or less bad, than starving to death, without saying whether slavery is morally good or bad, and being able to say this seems to me to be useful in the making of moral decisions.

This perhaps isn't a moral choice. But if you had to choose whether someone else lived in slavery or starved to death, it would be a moral choice, and saying that both are always wrong would not help you make a decision (although I imagine you would, like a utilitarian, look for other, more good/less bad, options).

I'm not sure what do you mean by 'freedom'. Could you give me an example of someone making a decision in freedom?
Thomas wrote:Utilitarianism and maximizing economic efficiency is identical if one assumes that (a) willingness to pay is a good measure of ones utility, and (b) everyone has the same utility for each extra dollar of income. Of course, there is no philosophically compelling reason to define utility in terms of (a). But it has the advantage that willingness to pay is observable and determines what happens, while utility in the abstract doesn't. The assumption in (b) runs into problems when you're looking at transfers between people whose marginal utility of income is different: poor to rich, askets to materialists, and so forth. So the rule "maximize economic efficiency" isn't the same as "maximize aggregate utility", but it's pretty good as a first approximation.
This is not a point of view I have come across before, thanks. You state that this system uses willingness to pay as a measure of ones utility. It was my understanding that utilitarianism was concerned with the utility
of something to people, not the utility
of a person, as seems to be the concern in this system. Is this a fair assessment?

I am new to, and so still grappling with, this concept, so forgive me if I am missing the point.
The first thing that struck me was that, when talking about buying an extra percent, no time scale or frequency of incidence was mentioned. If I were asked how much I would pay for one percent less chance of dying in an accident, I'd want to know how often I am likely to have the accident in question. If it's every day, I'll pay all I can for every percent up to 100%, if not I'll likely be dead in 100 days... If it's once in my life, I'll pay less, at least in part because I might need the money for other things which might shave a percent of something that might cause me to die.
As I see it there are two things we can spend money on: (a) quality of life, and (b) likelihood of staying alive. The article seems to suggest that the higher (a) is, the more one will spend on (b). But this only tells us something about a persons situation, not the value of their life. If it seems to say that likelihood of staying alive is worth more the higher (a) is, then it also says that quality of life is less important the higher (a) is. So, if future generations' likelihood of staying alive is worth more, then their quality of life must be worth less. This seems to me to balance out to say that all lives are worth the same:
If person x has high (a) then we should spend more money on increasing (a) and less on increasing (b). If person y has low (a) we should spend more money on increasing (a) and less on increasing (b). The question is only whether the money should be spent on increasing likelihood of staying alive, or increasing quality of life. The worth of the life is the same.
