Isn't an accusation of "bragging" just an admission of your inferiority?

For instance, all of the facts I mention in the course of conversation here are perfectly acceptable amongst my peers. If I'm sitting amongst a group of doctors and speak about my Jag, one of my peers may respond in kind with a comment about his Benz or Audi. If I'm amongst a group of car enthusiasts and mention how my lap times were faster in my Vette than they were in my 911 Carrera, they may simply nod and respond how their best lap was run in their R8.
One can even speak in this manner amongst those who are a rung down the socioeconomic ladder, because those people have a reasonable aspiration - even expectation - that in a few years, or after their next promotion, the same will be within their reach. Reactions may border on admiration or mild envy, but will never approach pure jealousy. If anything, it will inspire them to work just a little harder.
Yet one has to constantly walk on eggshells around here because of the insistent whining, crying, and other displays of jealous rage. It's only considered a "brag" if you KNOW it is forever beyond your reach. Otherwise, you'd be happy for others regarding their success. Accusing successful people of bragging is just admitting - nay, broadcasting - that you are vastly inferior.
I'm making a motion for the establishment of an "OT Poors Board" - too often it feels like I'm walking in a Walmart around here. Let the ballers mingle in peace. Do I hear a second?
