I don't have to try.
Look at the ships.
They are old ships hotrodded beyond their design specifications.
The Y-Wings are Old Republic era ships stripped of their stream lining for east of access and to recycle the unneeded metal.
The equipment is covered in dents and scratches.
Almost everything in the Yavin base are moveable modules (they found the buildings and moved the equipment in).
We see the same equipment again on Hoth and on the fleet ships.
The Rebels are a scattered make do and mend organisation.
The only way they get replacement materials is when they are donated by new arrivals (which are also old ships).
This is why the story of them fighting the mechanised established galactic government is so compelling.
It's the story of every resistance organisation on Earth but with spaceships.

Don't be ridiculous please. Every military airbase has reserve pilots. And to expect poorly equipped rebels to have more equipment than manpower is flat stupid.
Reads like you calling me ridiculous and my expectations stupid. you can do that sort of thing and more on the off topic section.
