**The point is that there is no direct correlation between how hrad someone works and how much they get paid. **
This I can’t agree with. All else being equal, the person who works harder will go farther and be more successful than the one who is lazy. How can that be in dispute?
Success in school depends in part on intelligence, but also on work ethic. The kids who grind it out and forego watching TV every night in favor of doing homework do better than students of the same ability who do the minimum. Those harder working students get into better schools, get more scholarships, and perform better in college because they are better prepared.
Take two people who are unemployed - the one who works harder at finding a good job is more likely to be successful. I know people who, when unemployed, fire out a couple resumes, answer a few ads, and then sit on their asses while their insurance runs out. Others pound the pavement, take resumes personally to companies they would like to work for, study hard to improve their skills while they are looking for work, etc. Guess who’s more likely to be successful?
In the company I work for, employees are rated as A,B or C. A is the top 20%, as ranked by their managers. B makes up the bulk of the work force, 70%. The bottom 10% are the ‘C’ workers. The 'A’s get raises of at least 5% above inflation per year. the B’s get cost of living increases and maybe a touch more. The C’s get nothing and lose ground - the message is shape up, or ship out.
The difference between these groups is rarely due to intelligence. It has more to do with willingness to take initiative, lack of sloppy behaviour, and work ethic. In short, if you’re always exceeding your manager’s expectations, you’re going to be an ‘A’. If you just do what you’re supposed to and no more, you’re a ‘B’. If you’re always late, try to cut corners, turn in the absolute minimum and no more, have a reputation for griping or annoying your co-workers, or in other ways are a liability to the company, you’re a ‘C’.
The difference between these groups economically is HUGE. An extra 5% in raises will double the salary gap between an A and B within 15 years. Almost all the promotions come out of the ranks of the ‘A’ employees.
As a result of this system, we have employees with no degree at all or with 2 year tech diplomas making twice as much as employees with masters degrees in computing science. I’ve watched people start in our company as junior developers and rocket past people who have been there for years and wind up as their team leader and eventually as a development manager or better.
And the one big difference between the three groups is work ethic. Oh sure, some are really bright guys. But the grinders do almost as well.
If I were to pick one characteristic of anyone that was the best determinant of their success in life, I’d have to pick work ethic as #1.
