One plan was already deployed, that was the segwit activation, but wallets and exchanges are still taking to long to adopt it. I mean do you have a segwit enabled wallet right now? If you had, and other users had it to, and exchanges, etc, the fees would be a little lower, just because of that.
The other plan, is of course the development of the Lightning Network, and that one should solve the problems once and for all. The problem is, that no one knows when this will happen, and people are not very patient normally. Bitcoin exploded to soon, and most people are just searching for fast profits, and don't understand that they need to wait for the technology to mature.
