But while there are poorer people driving for Uber, etc., the existence of dilettante drivers is very much a problem for those poorer drivers.

It's like special offers in shops; for someone like me who has spare money and plenty of storage space they are great, but for someone genuinely poor they are often unusable either because they don't have the cash at that moment or because they have nowhere to store it.

It's expensive to be poor. See https://wiki.lspace.org/Vimes_Boots_Index

You are right of course that fixing the poverty is the right thing to do.
