Relationship Between Money and Happiness?
Generally, when people think about happiness, they judge it by income.  The first instinct, as humans, is to naturally judge our success and happiness based on how much money we obtain.  People not only judge us, but when we stop, sit back, and evaluate ourselves we too judge our happiness on how much money we annually acquire.
Sure money does make things flow easier from day to day and month to month, but can it truly buy us happiness?  In 2010, a new world wide study was done to review peoples’ thoughts on if money can buy happiness or not.
The researchers found…
Life satisfaction was directly and strongly correlated with income, with the impact felt equally among all ages, men and women, and rural villagers and urban dwellers in virtually every corner of the globe, the researchers reported in the Journal of Personality and Social Psychology. Although money also influenced emotions, the effect was much weaker. Both positive and negative emotions tended to be affected much more in relation to other psychological and social factors, such as feeling respected, having autonomy, strong social support and working at a fulfilling job.
So money may not necessarily be able to directly buy you happiness, but it can buy you tangible items that, in turn, can make you happier.
The tipping point to where happiness seems to equal out amongst the elite and the lower/middle class is around $75,000 per year;  meaning that people whose salary is $75,000 and up per year report being just as happy as someone whose salary is, for example, $1,000,000 per year.  Therefore, people who make under $75,000 per year report being slightly less happy than those who make over $75,000 per year because having enough money to scrape by can be an issue which can cause stress which then finally can cause someone to feel unhappy or less happy.
Yes, Money Can Buy Happiness . . .
