The Covid and the new League for sure have brought old players back but imo there is a lack of young blood, I am eagerly waiting for the launch of osrs on steam, that should bring some noobs into the game :)
In the past I worked at construction, for the last 4 years been goldfarming osrs, which yields around 2k month, thats almost double the average salary to where I coming from. Also do stocks and recently got into programing.
