rich is bitch

maybe; Money doesn't grow on trees OR A fool and his money is soon parted. In English, money isn't talked about as a person so it doesn't have a personality or personal traits. You can, however, speak about 'luck' or 'love' as if they are people.

I think :wealthy is irresponsible. or richness is irresponsible. I am not sure is it correct. because I am not native speaker.
