To my mind when price becomes high, we have to pay low fee and when it becomes low, than fee has to be high. To my mind it had to be done like this from the begining.
I also remember that I could send any transaction with normal fee and receive confirmations in a few hours.
Recently, I had to wait more than 24 hours for confirmation and because of this experience, now I send each transaction with higher fee.
Yes, I don't like it, but still is cheaper to send funds with bitcoin than with paypal or WU, for example.
It's obvious that this situation must be resolved somehow because bitcoin may become less attractive to the new people.
I don't think that transaction fee is connected with btc price.
