Money can buy happiness.
I'm not sure what the debate is.
Have you seen and heard the delighted chuckle of a child when you buy him/her an ice-cream?
Have you witnessed the grateful smile of a service worker when you give them an extra tip (which, thankfully, isn't a custom in Singapore)?
Have you experienced the wide grin of a person in need when they are offered a sum of money to cover their daily necessities?
Is money the only way, the best way, the infallible way to happiness?
No.
But it is a way.
Let people find what they want, the way they want it.
