Class is a system of power based on wealth, income and status, which leads to unequal sharing of resources and opportunities. Every society develops its own forms of class stratification patterns that benefit some and harm others. Various figures have tried to understand the meaning and purpose behind the class. Karl Marx's class theory states the premise that "the history of all hitherto existing societies is the history of class struggles." According to this view, since it emerged human society has remained fundamentally divided between classes that clash in the pursuit of different class interests. Max Weber added that there are three levels of stratification based on differences in wealth, prestige and power. Class for Weber meant groups of people with similar life chances, opportunities to improve the quality of life and achieve success. Based on this view of class, Pierre Bourdieu described social mobility, the movement up or down in society, and explained that a person's ability to move socially depends on a person's cultural capital and access to the tools that allow you to achieve your goals. Overall, these three theories address the fact that some groups have unequal opportunities due to the lack of certain opportunities
