Looking back at it, one of the things I loved most about the ORIGINAL (i.e. Captain Kirk) Star Trek was that money was never an issue with anything that they did. Their world was a vision of a perfect Marxist utopia, where everyone contributed according to their abilities and received according to their needs. Leadership was earned by merit and respect.
That show is a testament to the attitudes of the 1960's, when the competing ideologies of Communism and Capitalism made everyone at least try to pretend that they were aiming for the good of all humanity.
Alas, that all changed with the Stalinist degeneration of the Soviet Union, et al.
Star Trek "The Next Generation" talked about credits regularly, although it didn't subvert the "good of humanity" theme too much.
Then, with Star Trek "Deep Space Nine", the show took a dive with the rest of American society, and glorified pure Capitalist greed with the Ferengi et al.
I hate that show.
Maybe now, with our *real* planet facing *real* environmental annihilation -- could we please quit talking about money and talk about humanity again ?
