In addition, different ranks of nobles and citizens have corresponding rights.
For example, nobles can marry unlimitedly, they have the priority in using public transportation, and receive priority in medical treatment, etc.
The emergence of the class system successfully ignited people's ambition.
Some strive for fame, others for the future of humanity, and some simply want to marry multiple wives.
But no matter their motivation, they all contributed to the development of human society to some extent.
Consequently, schools also made corresponding adjustments.
First of all was the curriculum. Starting from high school, subjects were divided into arts, focusing on humanities and mainly studying entertainment.
On the other hand, science was focusing on natural laws and mainly studying the universe's principles.
The ratio of these two fields often reached nine to one.
