I think they OT like crazy cuz they dont know a lot of stuff. If you are really good at your stuff, you can easily 3x to 5x doing it faster than others and with better results. Take an example mobile app. You take noobs like seeders that barely pass because of low hiring bar. It will take them like 1 month or even 2 months to finish to do list app. But for someone who is really proficient at android development, they can easily finish the app in 1 week with much better results and less bug.
