"Now, Captain Kirk, why did you order that man to investigate the giant monster?"
"He was about to speak, and we couldn't afford to pay him for that, as we only have five spacedollars in petty cash."
"We apologize for the necessity, Captain Kirk. You see, we're doing away with money."
Wouldn't the Thasians have restored them?
Sadly, no...
THASIAN: "We are saddened that his escape cost the lives of the first ship. We could not help them..."
I don't remember what Charlie said in the episode, but in the Blish adaptation he said "there was a warped baffle plate on the shielding of their Nerst generator. I made it go away," making the ship blow up. Later the Thasians explain that they can restore everyone else because he made them "go away" still whole, but the ship basically exploded on its own and they couldn't do much about it. I suppose they could restore the baffle plate!
Do we have any idea what the redshirt contingent was of a TOS-era Constitution Class starship? If redshirts accounted for more of the crew than any other group, it shouldn't be so alarming that the number of overall losses reflect that ratio.
When we talk about "redshirts," we really mean security guards. Red was the color for engineering and operations as well as security, but the vast majority of the "redshirt" fatalities were security personnel. It stands to reason that security guards would be the first in harm's way and thus have the highest casualty rates. Their job is to risk -- and, if necessary, sacrifice -- their lives to protect the rest of the crew.
I don't have numbers, but in VOY, it seemed like the majority of the deaths were engineering personnel.
I don't believe, in universe, the deaths are seen as a source of amusement or celebrated.
They're not, but it seems almost as bad at the end of any episode where the crew lost redshirts but the characters still stand around joking.
"Doctor, do I understand him correctly? Are you casting me in the role of Satan?"
"Well, Jim, you have to realize how insensitive you're being, considering how many friends you sent to their deaths today. Not to mention you fired Mr. Scott."
"It's okay, Bones, he's wearing a red shirt."
"Damn it, Jim, he's already been given plot immunity! Nomad killed him two episodes ago and then brought him back!"
"Hmm, at least we won't have to pay him anymore."
"Captain, that statement seems illogical."
"Yes, well, gentlemen, I have some bad news. Speaking of lack of sensitivity, I received word from Starfleet...."
