to increase profits by minimizing competition

Explanation:

In late 1800s, United States still hasn't passed any particular low that prohibited the practice of monopoly. Because of this, big corporations at that time tend to find ways to do it in order to take complete control of the market that they're in.

One of the tactics that they often did was Buying out all the companies in the similar market.  This will ensure that there will be no competitors that can become a second option for the consumers even if they put a high price on the market.

the caste system in india is the paradigmatic ethnographic example of caste. it has origins in ancient india, and was transformed by various ruling elites in medieval, early-modern, and modern india, especially the mughal empire and the british raj.it is today the basis of educational and job reservations in india.it consists of two different concepts, varna and jati, which may be regarded as different levels of analysis of this system.

the caste system as it exists today is thought to be the result of developments during the collapse of the mughal era and the british colonial regime in india. the collapse of the mughal era saw the rise of powerful men who associated themselves with kings, priests and ascetics, affirming the regal and martial form of the caste ideal, and it also reshaped many apparently casteless social groups into differentiated caste communities.the british raj furthered this development, making rigid caste organisation a central mechanism of administration
