Hello, very good morning. It's a pleasure to greet you again. Square Box is your place to discuss and ponder the Cuban economy. In recent weeks we discussed the economic and social changes in the country. However, an economy needs its workers to be able to develop, to have the conditions and incentives to achieve greater productivity. How can we make labor reach its value again in our country? How does this affect issues such as immigration, also the aging of the population and especially the recent transformations that have taken place in various sectors?
