By “streamers” you mean the streaming services? I think you grossly overestimate their power and influece. Without the major labels they have no business… literally. They are completely dependent on the major labels giving them the license to play the music that almost everyone wants to hear. The major labels set the terms, and if they want to change they royalty model, the royalty model will change. If they don’t, it won’t change. It’s that simple. Here’s a little secret: the services would love to change to subscriber share. Fact. Don’t tell anyone I told you.
If everyone is subscribing there will be a lot more revenue to spread around. So there’s a coherent argument that lowering the rates would be better. However this would hurt emerging artists more, and weirdly major label cash flow likes the emerging artists to be paid more (they are unrecouped). The bottom line is I think the $10/month is here to stay for a while.
