It can, if you are comparing between similar positions. Comparing the environment of an In-N-Out engineer to a Google engineer is valid, and so is that of an In-N-Out cook to a Google cook. But I don't think that knowing whether life of an average Google employee is "better" or "worse" than that In-N-Out is gonna be useful or illustrative of anything at all to an average In-N-Out employee.

It's like making a lawyer compare his workplace to that of a surgeon at a private practice, you are comparing apples to oranges. In part, because the chosen field in itself affects the workplace environment, and there isn't really a good way to separate the effects of the field vs. the individual workplace environment for the purpose of that chart.
