I guarantee you, and anyone else reading this, that with very little information I can predict with high accuracy how much money you make.
- Where you were born
- How much money your parents make
- Your health status at birth
- What college you went to, if applicable
- What you majored in while in college, if applicable
- How much your prioritize making money
I hate to say it, but the #1 predictor of your income is your parents' own situation. So if you want to make more money, be born to better parents. They will gift you the health, genetic advantages and socioeconomic circumstances that will statically make you succeed.
For everyone else, understand the rules of the game and bend them as much as possible. One thing I hate about working at Google is the sheer amount of out of touch engineers here. Everyone is so nice and friendly, but as soon as you talk about anything related to money you can see that some people are living, in a matter of speaking, on another planet.
EDIT: Looks like the post was edited to be removed. Basically the OP was saying he made 400K+ at Google and their significant other made another 200K as a car salesperson and they are both "run of the mill" at their jobs. The OP then goes on to say that if you try hard enough it's pretty easy to get to the position their at.
Ironically the reaction of removing the post is exactly the same sort of reaction I get in person in when money or money related matters is ever the subject of a conversation with someone who is an engineer at Google. If a non-engineer is in the conversation the engineer will just say life isn't fair and leave.
