Do you really think "my only interest is money" is a balanced comment? I don't see how this even makes sense. If you didn't have other things that you wanted to spend the money on then it wouldn't be much use.
They said that they aren't only focused on money now, and that they care more about doing things they enjoy, pretty much the opposite of "my only interest is money". You should read the comment again, since it looks like you rushed to call them selfish without even understanding what they said.
Well they qualified that statement with 'I literally have enough money not to worry about it and now my interest is in the things I spend my money on' so I'm not sure if that disqualifies what GP was saying. It's easy to say you're not solely focused on money anymore when you have enough money to never worry about your financial security again.
