On Wordpress I use wordads, and yes, it is similar, even if they let any users with a premium account use ads on their blogs, the withdrawal cap is 100$, and since the competition is steeper there, similarly than on youtube, you make maybe $2 per 1k views there. And you absolutely need a huge visits influx to get anything, because even if you get a steady 30 views a day, it counts for pennies in the eyes of ad programs.
It sounds to me like you don't know how to grow these different mediums you've created for yourself. It's definitely a steep competitive world, all that, but it is winnable. There's a subtle sense of you blaming these tools, but if you haven't been able to reach the minimum withdrawal limit in a dozen years, there must be something you can do on your end to improve earnings.
Doing this would really help you overall, because I remember our conversations from before about jobs and whatnot.
