Well, who takes more risks than explorers?
No stations near by for repairs, unknown systems where you are taking heat damage before you even finish jumping in, constant wear on subsystems - and all for the lowest paid career in Elite: Dangerous.
And to quantify that, a friend of mine went out to Sagittarius A* and back, scanned everything both ways - picked up less than 2 million for weeks of work.
Traders can earn that in 30 minutes or less,
Miners in a few hours depending where they mine.
Bounty Hunters, 2 hours or less in a semi good RES,
Pirates are hit / miss depending where they are or who they see.
All of the above are near stations and can get repairs if they end up on life support.
25 minutes of life support is no good to an explorer, depending how far out they are 25 days of life support can be pointless.
People love to spout "risk / reward" for traders and pirates - but people ignore the highest of risks with the least rewards, exploration.
