How much are Sherpas paid on Everest?

I'm curious to know, just how much are Sherpas actually paid to work on Mount Everest? It's a dangerous and physically demanding job, so I'm wondering if their pay reflects the risks and efforts they undertake. I've heard varying reports, from meager wages to significant sums, but I'd like to get a clearer understanding of the compensation they receive for their invaluable services.
