I think they really don't know how bitcoin works and what its give to their life, they are not open minded person or they just not interested and they are content what they already have.
instead they do not know how bitcoins work but they want to work with the results of their own sweat and feel how to make money using their own energy. bitcoin is easy and instant, we just face the computer and internet after that think what we want to do with bitcoin. one's interest is different so we can not prevent it.
