In reality money is what brings the happiness. Some may agree or might disagree. For example, I'm a true believer in the quote; money makes the world go round. If we didn't have money whatsoever in this world then, what would life be like? We would all be poor and depressed.
I'm here to prove to you that money can buy happiness although people seem to think that just by having lots of money, you can only buy materialistic items or possessions. That's not always the case. You shouldn't presume that just because someone's got a wealthy bank balance, it doesn't mean that they are living the life of Riley. You can do many other things with your hard-earned cash like, help the poor, take loved ones on wonderful family vacations or help dying people by donating money.
Lets use an example here, this won't apply to everyone but its an example. So what if you're parents came from another country and before they die they've always wanted to visit their home country or visit a beautiful place before they pass, wouldn't it make you happy to grant that wish for them? Therefore it can buy happiness in some ways. Don't always think that people have plenty of money to splash out on luxuries, even though they could... there's other ways of looking at these situations instead of making judgement.
Many people will say that Celebrities are bad influences because they flaunt their cash with fancy cars and millionaire mansions, People shouldn't be so quick to judge, just because they may work extremely hard for their money, it doesn't mean they get their money for free. I'm sure if you were always in their positions, you would feel happy and rewarded for your hard work and treat yourself regularly.
Being realistic in general, I'm not saying money is everything but you got a roof over your head, money to buy your food... what if you didn't have that and where would you be without the money to afford those things... Would you be happy living on the streets and happy to beg for money? No you wouldn't. You can't deny the fact you would feel depressed. So can money pay for happiness.... Yes it can!
