Do you agree that no matter how rich you're, if you don't have friends you can't be happy ?

Nope. Don't need friends, don't need no one as long as I have dosh. ┏ʕ •ᴥ•ʔ┛

Rich people all have plenty of "friends"

Friends are what make you rich.

Trumpski is a good example of that!

Nope.

Depends, "old money" people have different values and tend to be more down to earth than the "noveau riche" who are more often affected, stingy, often rude to folks who have little.

here is the exact key to being happy financially. you need enough money, to have enough time, to do what you want to do, when you want to do it.

Having wealth is important, so is having friends.. Although I think the two ideas do not/may not/have to.. be related..

Nope. I have money and I'm doing ok for myself. Friends eventually screw you over.

Nope.
