Experiments with rats:

When I once again saw how on the street the parents cried out on the child, I realized the deep problem of our society: the rule is considered the right of the elderly to violence against the younger, physical or psychological. Parents torture children, old servants - recruits, chiefs - subordinates, officials - applicants, etc. The seniority is considered by age, rank, position, etc. The focus is that this right to violence seniors receive not for their merits, but for the time spent in the corresponding system: family, army, institution or corporation. When the elderly were younger, they were tortured in the same way they are tortured now. The position of the elders: "We suffered – now you suffer". That creates a vicious circle, from which only gifted people are chosen, through long reflections on themselves and society. Their children have a chance to grow up with fewer complexes. On the other hand, the upbringing of the younger is a difficult work, and it is easier to conduct it with the help of violence than most do, similar things produce similar, unhealthy individuals raise the same. In short, we are almost no different from rats, biologists believe that humans are 99% the same animal with a slight plaque of mind above.
