People are happy if they are healthy, well fed, see the people they care about are happy, don't live in anxiety all the time, and feel what they do day for day has some kind of meaning.
How that is achieved is secondary.
If someone feels like a faceless drone and constantly has to worry about how to make it through life after retirement, neither a 3000$ gaming PC nor a trip to Bali is going to make them happy, both are just bandaids over the misery.
