Money can't buy happiness. Yes, they can.

A limited amount of money can bring you happiness. More or less leads to disturbing the balance in your life. 450,000 people surveyed by Princeton researchers set the money limit for the perfect balance between finances and well-being at $75,000 per year.

What people call a 'decent salary' is that which allows them to live a comfortable life: enough money to cover all the expenses during a month plus something extra.

Another money-related issue is the salary secrecy so popular within companies. Many believe that people would be happier with their jobs if salaries would be transparent for all the employees.

New York Times editor, Jill Abramson, explains how mentalities are now and how they would change is payments were known to all workers:

'Since companies tend to be run by people who earn a lot of money, the result is a culture of silence and secrecy when it comes to pay. For one thing, secrecy about pay is bad for women, who are worse at asking for raises than men are. Secrecy around pay is also a great way to allow managers to — consciously or unconsciously — play favorites with their staff.'

By engaging in a simple exercise of imagination, it is easy to see why working in a company with visible employees wages would make them happier.

'If you work for a company where everybody knows what everybody else is earning, then it’s going to be very easy to see what’s going on. You’ll see who the stars are, you’ll see what kind of skills and talent the company rewards. You’ll also see whether men get paid more than women, whether managers are generally overpaid, and whether behaviour like threatening to quit is rewarded with big raises. What’s more, because management knows that everybody else will see such things, they’ll be much less likely to do the kind of secret deals which are all too common in most companies today.'
