I suggest the book "Into Thin Air" (and the movie version "Everest") if you want to know more about how the commercial side of Everest climbing works (and about a really sad tragedy).
Do you climb mountains? It's hard to explain the motivation if you don't do it yourself. Most people I know who have done big climbs are not trying to impress their kin. George Mallory answered the question why with "Because it's there." That's still about the best answer.

Take the Alps for example. On one day in the summer of 1979 12 people died on climbs around Chamonix, which is a single valley. It was a beautiful day with ideal climbing conditions around much of Mt. Blanc. I remember it well, because I was in the valley watching helicopters bringing down bodies all afternoon.
Most of the deaths were on the Tour Ronde. [1] The uppermost of 3 climbing parties fell on a steep couloir and took out two parties below them. Perhaps the first party was unqualified but the second and third parties?

What kind of brain injury do you have to have to want to pay $50,000 to stand in line for that?
Personally I don't care about doing it this way and I'm pretty sure I couldn't do it how real mountaineers do. I'm not bitter, I just think that what they are doing is a farce.
Kudos to those that attempt the ascent after years of real training and knowing what they do.
If you enjoy rock climbing or mountain hiking you go to one of thousands of other mountains. There are plenty of places that are more challenging if that is what you crave.
Literally the only reasons to climb Everest in the modern day is because you want the egocentric talking point of having climbed the highest mountain. That or you like queuing at high altitude.
