Since everybody's cheating money, it all cancels out! So nobody is cheating anybody money, the only ones getting cheated are the ones at the bottom of the society.

And actually, engineering seems like the least of all cheaters, because there are many times when you just can't produce something due to lack of knowledge, skills, tools, and resources, and this is proven when a DIY effort turns out more expensive yet inferior.

No wonder it is strongly advised to avoid taking up engineering as any form of professional career, and most successful engineers convert to businessmen instead.
