<span>The Vaishya failed to change their status but gained other advantages. Since 1950, the country has enacted many laws and social initiatives to protect and improve the socioeconomic conditions of its lower caste population. These caste classifications for college admission quotas, job reservations and other affirmative action initiatives, according to the Supreme Court of India, are based on heredity and are not changeable.[16][a] Discrimination against lower castes is illegal in India under Article 15 of its constitution, and India tracks violence against Dalits nationwide.</span>
Flawed judicial system? Not enough government funding? Unhappy citizens? I can't answer your question without context.
1) Population curb: After the Europeans became extremely strong, they forced Indians off their homeland and placed them in reservations and such.
2)Disease: Disease brought by Europeans (i.e. measels, chicken pox, etc)
These impacted the American Indians more than weapons and technology of the days
3) Technology: Technology would be the next. As many Indians gathered and hunt (yes some did farm, not a lot, and with primitive tools), there tool weren't as enhanced as the Europeans (for example, they use wooden plows against the European iron plows. Or they still use wooden spears with hardened points or bows made of wood and arrows with stone points. On the other hand, the Europeans used muskets (IDR if they invented rapid-fire yet or not) body armor (knight's armor type, kinda like conquistadors) and cannons, etc. Technology helped Europeans both gain allies and defeat their enemies relatively easy.
4) Allies and Enemies: As Europeans allied themselves with certain tribes, the other tribes would feel unsafe and the sort, and would make war. This led too numerous wars, and the fall of many Indian tribes (and European powers. Take for example, the French and Indian war).
5) Crops: Europeans introduced many different crops that were later part of Indian food life and the sort. These include wheat, barley, rice, turnips, etc. Some of these crops impacted Indian life, and became one of the many foods they eat.

They have been looked down upon for decades and possibly centuries. It had become a sort of a social norm in a sense to view them that way, hence all of the public opinion has shaped how we think of them today.
