Fees are not the problem, scaling is.
Someone here said that the miners will just "spam" the blockchain with their own transactions (they will just be paying themselves the high fees) to make the blocks full again, so scaling won't resolve the high fee.
"Someone here" is making baseless speculation.
This has never been done before to a troublesome degree. So why would miners do it now? Did they just suddenly decide to go rogue and attack Bitcoin?
Not only that, such an attack would be unaffordable to maintain.
Before scaling was ever an issue, Bitcoin ran fine. The blocks were not full, because there weren't that many transactions.
Wanna know why? Because there weren't any miners spamming the network (and there won't be), but there also weren't many people using it (and now there are)
To make your own point somehow different from "baseless speculation", you would have to answer a few simple questions yourself. In fact, just one simple question. To wit, you would still have to explain who is behind the spam attacks. If miners can't allow to run the costs of these attacks, then who is running them, after all? If mining is heavily centralized, there is more than enough economic reason for miners to collude and spam the network with these useless transactions. Since they are the ones who will be receiving the fees, the whole shebang becomes perfectly feasible and makes perfect sense from a financial point of view. In fact, it would be quite profitable if the miners managed to bid up the fees through that
Which seems to be the case as we actually see the fees escalating
