You have listed three items as necessary. You are confusing physical suffering with unhappiness.
Health can reduce any happiness from happening. state of mind is reflected in the state of body.
Intelligence causes more suffering because a person can find new ways of suffering
Many may not agree with this
Wealth has nothing to do with happiness.
An assertion. no proof
As shown earlier, to rebut a claim all one needs is a counter example.
As replied earlier, this alone is not sufficient.
Homeless and Sannyasis have no wealth and yet many are found to be happy. Many such people do not know where their next meal is coming from. Yet they are happy. No all Sannyasis or homeless people. But there are enough that are happy and will say so. Your list of necessary condition is not correct
what weakens your argument: Sannyasis try to transcend physical existence and hence are able to be happy and even blissful without the mundane requirements of happiness
People who suffer and are terminally ill and hence choosing assisted suicide have reported enormous happiness and freedom. Just google for such people
again more an assertion than good reasoning and is at best a flawed reasoning
If you are truly curious and have the humility to listen to words of people who have done real research then Google for 'The Happiness Project". It is a well rated book and provides extensive research. I saw this book in someone's home and was curious. It cites historical studies that will refute whatever you have been trying to say here.
Thank you for the reference. I talk from my own experiences to which I think people may relate.
Your list is arbitrary and is not a fit with eastern or western thoughts and as shown above is not logical.
You need to work on stopping at assertions and do some real logic
