What is the manifestation of injustice and cruelty of people?

In the modern world, everyone is faced with the blatant injustice and harshness of the people around them. Even close people are capable of being mean. Injustice is expressed in the fact that a person does not receive what he deserves (hard work does not always bring a high income). The cruelty of people is manifested through: indifference to nature and global problems, indifference to other people’s troubles, the expression of feelings and emotions through brute physical force (fights, family violence). There is an unwritten law: every man for himself.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
