Looking at one of the latest blocks processed I noticed that the fees we pay today do not appear sustainable at all.

Block Reward $ 11,405.50
On that block miners earned an average of $5.56 per transaction confirmed. (from tx fees and the block reward of new generated coins)
But users only paid an average of 33 cents per transaction. (which seems kind of high to me as I never pay that much)
Once the last bitcoin is mined will users be asked to pay 5 bucks plus per send?
If so, how the hell is that going to be sustainable? Competition will kill it wont it?
