What is the difference between the $20k/year vs. $250k/year software engineer?
For example GitHub web code editor that scans thousands of characters after every key stroke for emoji, tons of exploit with obvious issues, Twitter web DDoSing itself, code-mess in Facebook (What I have heard) and lots of other example. Don't tell me, they didn't have enough time, there are literally thousands of people.
Why should companies hire developers with 250k salary who will spend most of their time doing nothing instead of someone with 20k salary?
