Consumption has a great relationship with the supply and demand of the people. For example, in Cuba a month's salary is not enough to buy the necessary food for 10 days. However, the number of businesses and markets has increased. I have sometimes wondered: Will it be appropriate to maintain so many private markets. It is true that today the basic needs of the people are met in these places. But how to maintain this pace, if the price of the products exceeds the value of the income? Some benefit, the minority. Really worrying.
