Consumer advocate: Economists reason that price gouging—increasing the price of goods when no alternative seller is available—is efficient because it allocates goods to people whose willingness to pay more shows that they really need those goods.
Conclusion (implied)
This argument claiming that price gouging is efficient fails.
Intermediate Conclusion (as a result)
Price gouging will not, as they have argued, end up allocating goods to the people with the most need for those goods.
Intermediate Conclusion
A person's willingness to pay for a pricey item is not proportional to their need for that item.
Premise
In the real world, no matter how much you need something, you just might not be able to pay as much as others can.
Evaluate
Whenever we read Role or Main Conclusion, we prime our brains for arguments that put the conclusion in the very first sentence, or arguments that start with another point of view and then pivot into the author's rebuttal.
This was the latter style. When authors rebut some initial position, the conclusion can sometimes be implied. We want to feel these arguments having this sort of chronological structure (usually):
1. Some people say X 2. But I, the author, am concluding maybe not X 3. Here's why (here's my evidence)
There might be intermediate conclusions within #3, but we don't want to lose sight of the fact that these intermediate conclusions are still serving the purpose of supporting #2, which is the author's rebuttal to #1.
Here, we're being asked about "willingness to pay is not proportional to need". This is part of how the author rebuts the economists, so we can say it plays the role of Supporting his rebuttal.
But we can also call this claim a Conclusion, because it's supported by the second to last sentence in the paragraph.
Goal
Look for something saying this claim is part of how the author rebuts the economists, or something saying that this claim is a conclusion supported by the fact that .
