Lenin said giving the right to rain to umbrella sellers. If I leave the rain to the umbrella seller, Lenin said. This is a famous saying by Lenin, which means that if the right to rain is given to the umbrella seller, will it stop raining? As long as it rains, there will be people buying umbrellas, and businessmen are all seeking profits. This sentence was said by Walter. When people realize that the right to rain is determined by selling umbrellas, everyone already has a durable umbrella with them, and sales have hit the ceiling, and there is no antagonism between demand and market.
