Not many climbers on this forum then! lol
Yeah its expensive to get to everest, also the sums suggested here are vastly under the real amount, in reality to make an attempt at everest with permits (depending on the operator and country you do it from), your looking at £25,000/38,000 (bargain basement minimum) - £175,000 + (several sherpas and gear carried for you).
Even then, none of these companies apart from perhaps the most expensive (who have sherpas to carry even your o2 tank), would ever allow an inexperienced climber to go - most people who attempt it are experienced climbers, not professional climbers, but very keen climbers who work in other things, as far as im aware no novices have ever tried it as that would be certain death.
Sure several thousand have now done it, but non were run of the mill holiday makers - even the least experienced would have had a year or 2 fairly intense prep to get fit enough, however, if you have the money and the time, yes nearly 'anyone' can climb it - but its still one of the most difficult things to do - far far more difficult than running a marathon for example, don't let the fact a few thousand people having done it take away from how rediculously difficult it is to do.
