You know.. In these cases Id add a simple argument.
I make something from scratch..spend 1 billion dollars on it.. learn a lot in the process how not to build it the wrong way and finally build it correctly and feel good about it.
Then I learn how to tinker with it and improve on it.
The other guy spend 20 million to buy somebody else's thing which works already, Tests it out to his hearts content, learns all about it from the correct path and feels good too..except not only did he spend a LOT less money on it, He has something that worked perfectly well in the first place so now he knows which way to tinker with it to make it better.
SO.. while we both got the same thing, and I really worked my butt off, the other dude has the same thing, 1/8th of the effort, 1/20th of the price.. and still is showing it off at my face saying "Hey.. I got one too"
At that point Id feel really really stupid
