In my inflammatory opinion, hiring a guide as a teacher is fine, but hiring a guide to get a summit tick because you don't want to go to the trouble of making friends with other climbers or pushing yourself up the skills pyramid slowly is equivalent to using oxygen or pulling on bolts .
Look at all the dumb asses on Everest like Chossy Hill Pitman. Sounds like she could have just sat in a haulbag and been winched up the peak...
No offense to guides but how can you respect some of those clients? Kind of like hookers and johns?
