because if they can charge you more for that ramshackle hut they will, housing is tied to who will pay for it, if the hypothetical burger flipper makes more, he or she is also willing to spend more of that on housing, as is every other hypothetical burger flipper, meaning the hut-lord can increase his price, as there is now more funds in the system, and more competition due to those funds, no new huts are built, so the price of all previous huts will just rise. Without regulation, this is how it goes.
