~m,
What triggers shame for me, is my negative response to the world, rather than something "out there". More specifically, comparing myself is not helpful, I find.
At the risk of someone out there labelling me as oversimplifying my life as "black or white", one does have to respond, and those choices ultimately impact our feeling state, and what we do the rest of the day, and how we interact with others.
I think there's an argument about whether the environment or myself is primarily a cause of a shameful set of thoughts leading to the behaviours and self-perpetuating lifestyle which follows, but I need to respond to the world in either a productive or non-productive way.
It might be different for you ~m, but I know I was set off today by those triggers, and had a miserable afternoon. Once I get going, focus on something productive, I dredge up something postive, and build on it.
Carl Rogers was a contemporary psychologist who believed in something called "unconditional positive regard", I believe. Maybe society has marketed "shame", since a newborn in a 3rd world country should have the same value as a newborn in a developed country, and both should grow up knowing they are of value, shouldn't they.
I think a lot of materialistic people think those children need "baby gap" clothing and ferraris when they grow up, and marketing shames us to buy stuff as "retail therapy", but it doesn't work, because the issue is one of self-worth.
