For me it is so high because the Bitcoin Cash, Bitcoin Unlimited, Bitcoin XT, Bitcoin Classic cartel is spamming the network in order to enforce their proposals, which are mainly destroying Core and increasing the blocksize limit.
No one is spamming the network. This was the case 2-3 months ago but after NYA it stopped.This is the amount of unconfirmed transactions in the last 60 days:
Right now OP is wrong. Network congestion is low and the fees are perfectly normal. You can choose to pay a lower fee and your transaction will still be confirmed, which was not the case 2 months ago.
