There is no point that as ever been clear and bold as this one, you nailed it right at the spot.
As a writer I want to earn £££££, but I understand the sheer number of available authors means there will always be someone who is either more skilfull, or willing to accept less in renumeration for their efforts.
This point you stated is really true and it happens all the time, people go for less expensive things and there are people willing to give even less more expensive not thinking of their efforts crating that project, and I guess there is a reason for that as well in Which you somehow stated too.
What a crazy world right?
