I used to run a music label and here's some numbers from 2012 to 2016:
Within my county, pay for 1h of live music dropped from ~$30/h to ~$6/h.
Average pay per streamed song dropped $0.03 cents to $0.007
Cost to belong to proper songwriting and such unions went up from $160/yr to $780/yr

Note that over this period, online piracy plummeted and subscriptions to streaming services rose dramatically.
Don't assume not pirating has improved things for musicians.
