I never flaunt wealth because it isn't important to me. Not being seen as the poor farang has its benefits though so I try not to be super cheap. Have no problem with others that flaunt their wealth and especially if they are living a satisfying life. The pretenders can be frustrating and are usually easy to avoid.
I have a simple home and a couple normal cars and this is what people see passing by. Functionality of what I possess, a good view from my home, comfort, a great partner, and being extremely fit are my drivers.
