No, it's all bullshit. There's a lot of talking and propaganda around these ideas but when you start peeling it apart it's just layers and layers of circular citations and dubious studies by (professional) social "scientists" ( yes, I do think we should go back to calling it social "studies" ). It wouldn't even be a thing except it's repeated often and loudly by entrenched, tenured activists in universities.
Yes, telling people to negotiate is absolutely enough to break this HABIT(yeah, this conditioning idea is a flat out lie). People who have never bartered for anything, and moreover have never even witnessed bartering take place make the adjustment on their first day in a new country. Go ahead explain how this is "different" and somehow not "conditioning".
The real problem is the people with a disproportionately loud voice telling us that we're all brainwashed and incapable of owning our lives and our minds --who then propose to fix it with their own brand of brainwashing that suits their own selfish agenda.
