Typically the greater responsibility you have the greater the pay, technology seems to be the exception to this rule. I'm always impressed by CEO's who take a small salary and align themselves with shareholders by focusing on options and shares. It's a big trend in technology with Larry Page (Google) and Mark Zuckerberg (Facebook) famously earning $1 in salary. Also joining them is Kosta Kartsotis the founder of fashion brand Fossil and Richard Kinder from the pipeline company Kinder Morgan.
As always Glassdoor is only a sample beginning 2017 public companies will be required to disclose their ratio of CEO to worker pay. It will be interesting to see if CEO pay rises ahead of this deadline and just as likely falls after the disclosure.
