It's a pity that people in Asia, Africa and Latin America always pay the price, and there are relatively few in Europe, especially after industrial revolution in europe. Because if we want to make progress, there will inevitably be many problems such as the transformation of labor force, production and production relations. There is a price every day, which is impossible.

On the way forward, mankind will always be like this, but today, if society wants to make progress, it will inevitably lose the interests of some people, even many people. For example, during the reform and opening up, the state put forward the slogan "Let some people get rich first". Then the price of people who get rich must be people who don't get rich, and this contradiction will always exist; But our society has also made progress, which is why we have achieved today.
