castism and economics

Over the centuries, Indian society is following cast system as a part of Hindu religion. For a moment if we keep aside its wrong customary implementation mechanism, it can be seen that it was basically meant to establish economic rules and regulations in the society. Every class/cast had specific functions to perform and had certain associated responsibilities and controls to perform them in a most efficient way. When it was flourishing society with economic stability, this was more of a beneficial system, but along with the fall of kingdoms and subsequent fall of wealth, cast system became stumbling block in a way of progress and eventually became a burden to the society.
We can compare it with the situation in today's industry. Lets take an IT company for e.g. Top management is like Kshtriya who hold the power, and technical Guru' can be like Brahmin, marketing and middle management are like vaishya, and other including developers are like kshudras. Its not exaggeration to think this way, because today economy is in good shape, so we don't really have it as a problem, but tomorrow if and when it goes down, this similarities will surface and there will be fight amongst these classes, like before. Surely today these are not linked to the birth and so may not seem to be of grave danger, but remember even chaturvarnya system originally was not associated with birth, but later in need to keep the control, higher casts enforced this to others.
Hope we learn something from the past, and change the system.
