As an experiment I did the assignment for @Eternity to pick a topic people would disagree about and write five one sentence arguments about it that you think are correct in under 15mins. Mine took about 30 mins. I also think 5 sentences are related by one main argument, and aren’t totally distinct.
The topic is: the use of price controls
Price controls that set maximum prices create shortages because their effect is to both expand the demand for a product and decrease its supply.
The goal of maximum price controls is to make it easier for marginal consumers to get access to goods but their result is shortages of the very same goods.
Price controls that set minimum prices create surpluses because they both decrease the demand for a good while maintaining its supply.
The goal of minimum price controls (for example minimum wage laws) is to help marginal producers sell their goods for more but their result is to decrease demand for the marginal producers goods.
In the same way, the goal of minimum wage laws is to help marginal workers but instead they have the effect of decreasing demand for marginal labour (destroying low paying jobs) and therefore creating unemployment for the same marginal workers.
