What did the Magna Carta do for human rights?

Les explains that throughout human history, unless one was among the very elite ruling class, life for most people was just existence under abject poverty, slavery, and oppression. He notes it wasn't until the Magna Charta came out of England in about the 14th century that it delineated some human rights. Before that, there was no such thing as human rights. Since the Magna Charta, Western civilizations have had at least a semblance of human rights. But Les points out that even among Western civilizations, many people still live in a downtrodden state; we are not in any utopia. We are blessed as a nation, yet many still grovel in poverty.
