I'm suprised that anyone can outpay Google by 150%.

Here is what usually happens:

A new company (google in this case) sets up shop and needs to hire top talent. They start paying really good salaries and sometimes they even add perks like massage, day care, etc.  They get to be known  for this and people start to ask to work there so they don't have to do anything else to attract top talent.

Eventually some other company needs to hire the same top talent so then the new company has to pay out the ass to make it attractive for people to work there. At some point google (for the example) can either up its salaries or they can keep good salaries (no major increases) while coasting on the reputation that they have built as a great place to work.

Go to bing and seach for sas institute. They used to be known in the triangle area for their perks. Now the things they offer are what you would spect from any big tech company but nothing out of the ordinary.

That's how you get companies that outpay google or any of the big names
