There is nothing wrong with the following:
- Being rich, or working hard to become that way
- Loving nice things
- Using your wealth to purchase nice things
There is something a little wrong with the following:
- Flaunting your wealth in an attempt to make others jealous, or imply that your wealth says something about who you are
It’s not a cardinal sin. It’s just silly, and tacky, and small. Enjoy things because you enjoy them, not so others know you can enjoy them. Think Warren Buffet, not Donald Trump.
