I think that if fees are too high, people will cease to use bitcoin and miners will cease to get fees so none wins. Probably they will adjust to a point of compromise.
People will cease to use bitcoin and miners will increace fees to save earnings. It will cause that people will cease to use bitcoin... Bitcoin going to be forgotten (unstable system).
I hope we have another way: People will cease to use bitcoin and miners will increace fees to save earnings. It will cause that people will cease to use bitcoin... Many miners stop mining --> Difficulty decreace ---> Not so many miners go back... Bitcoin not going to be forgotten (stable system).
