Money can very much buy happiness. Most of the things that make you unhappy can be remedied with money. How much money you need to accomplish that depends though.
The person you are replying to agrees that money can get rid of things that cause unhappiness. The point is that removing unhappiness is only part of what creates happiness, and money can’t buy the other part.
> Money can't buy happiness, but it can buy less unhappiness
> Money can very much buy happiness. Most of the things that make you unhappy can be remedied with money
Was it too hard to read beyond the first comma?
> Most of the things that make you unhappy can be remedied with money
Nonsense. Most of the things that can be remedied with money are not the truly painful things of life either.
Will money save you from heartache? From the pain of losing a loved one? From being lonely? From having no respect from your peers? From losing your health to incurable cancer?
At that point, all money can do for one is make them even more pathetic.
Unhappiness and happiness are surprisingly orthogonal. Removing unhappiness does not make you happy, it makes you not unhappy[1]. Being not unhappy is a requirement for happiness, but it's not sufficient.
1: not unhappy is weird phrasing. Substitute not sad or not angry or not hungry or whatever for your particular state of unhappiness.
