Haha. This one is kind of hard to explain. I see why you are confused. The sentence is basically an analogy. The "poverty market" would be one where prices are low because people in that market can't afford anything above the poverty level. Saying "you're in danger of pricing yourself out of the poverty market" would mean that you are setting your own price too high for the people you are trying to sell to. I would need to know the context that the sentence was written in to understand the full meaning the author was going for. It probably has something to do with making yourself out to be better than you really are or it could mean that you are making vast improvement and are close to moving to a higher level than your current one.

What is the context of this sentence?
