> The Varna system is an equally evil practice as it still creates hierarchical structures in the society and worse, it completely disregards dignity of labour

First read about the Varna System. Or at least watch the videos that I have linked ([1] and [2] — Discourse by Padma Shri Bannanje Govindacharya — was one of the greatest Sanskrit Vidwans of our times) to actually understand what the System was about. There was no hierarchy. The hierarchy came about in Jati/Caste System. Misinformation is worse than ignorance. Misinformation corrodes society. In the Varna System all the Varnas were equally important. Nothing was superior or inferior. All were Moksha adhikaris (or were eligible for Moksha). Even more so Shudras. Because everyone is born a Shudra. Doesn't matter what Varna he adopts later (this process is called Dvija or second birth — where he chooses to become Brahmin, Kshatriya, Vaishya after the Upanayana Ceremony).

Do you know the meaning of Shudra in Sanskrit? It is a combination of two words: "Shuk" and "Dra". Shuk means "misery". Dra means "melt". So Shudra is one who melts for others miseries. Shudra is the basic quality that defines a human being (one who melts for others miseries). You cannot be a human being without first being a Shudra. No where in the Dharma Shastras is it written that you have to discriminate against a Shudra. Most of these discriminations stem from medieval practices of Jati/Caste System which go completely against Dharma and should be abolished.

To give you few examples: There is a Vedic story (Chandogaya Upanishad) of Satyakama who was raised by his mother Jabali. When he was just 5 years old, he goes to Rishi Haridrumata Gautama asking permission to study the Vedas. The Rishi asks him who is father is. Satyakama wouldn't know the answer and says he'll enquire from his mother about the name of his father as well as his father's Gotra. When he asks his mother Jabali, she says that she worked in multiple homes in her youth and doesn't really know who his father was (or in other words she worked as a prostitute). Satyakama goes back to Rishi Haridrumata Gautama and tells him whatever his mother told him. The Rishi, pleased with the boy's honesty, declares that he has qualities of a Brahmana as he demonstrated that he did not hide his reality. And because of which his quality is that of a Brahmana. So is the true seeker of Brahman/God. Rishi Haridrumata Gautama accepts him as his disciple and imparts Vedic knowledge.

To make it even more explicit: All the Vedas were compiled by Krishna Dvaipayana Vyasa (popularly known as Veda Vyasa). Veda Vyasa was born to a Shudra mother (who was co-incidentally a fisherwoman by name of Matsyagandha/Satyavati; saying so because your username says "IndianFisherman"). That itself should make it clear to you that we did not have Caste System but Varna System. There was no hierarchy. This hierarchy came into play only in modern times. If the Compiler of the Vedas was himself born to a Shudra mother where does the question of Shudras being inferior to Brahmins arise from?

We all bow to that great Vyasa who gave us the Vedas.
