My experience on Upwork is actually the same as yours! In our tests of the platform, it appears to be very difficult to find jobs due to the intense competition. I was unpleasantly surprised at first when I saw how difficult it was to earn money on Upwork as a new user. However, that was the whole point of the initial tests we did, so we expanded and have still been expanding the program to encompass other forms of virtual work that pay reliably and still have room to grow. Upwork will be a minor or non-existent part of our program.

If my program was just on Upwork, then I would be inclined to side with your analysis. Thankfully, it's not.
