If people really paid attention to Star Trek, by TNG and Deep Space, Earth is ruled by if not “noble” houses but political or influential families. Kirk’s family, Riker’s family, Janeway’s family, were all connected to the space aristocracy.
“Try this. It’s a drink humans call root beer”.
YET, the Federation had "its" territory it would defend.
And there was rank in there were Admirals, captains, etc.
"Sir" is used only when addressing a male officer
or another male who is in a position of authority or
as a sign of respect to an older more experienced male
person such as one's father.
Applying "Sir" or "Mister" to a female would to
me come across as insulting a lady. Try calling
Queen Elizabeth II "Sir" or "Mister".
Kirk had money, he just sold the reading glasses he got as a birthday gift, at an antique clock shop. He then ensured the crew got a share of it. He’s just cheap.
That’s why she brushes him off at the end saying she rather hang out with the whales.
Money is not only a medium of exchange it is also a store of value. Even the most primitive societies had barter, exchanging goods for goods. The development of money very quickly followed. It is inconceivable that in some far off future that a highly advanced society could run without an economy based on some medium of exchange or store of value.
In the First Contact movie Picard was in the middle of a Borg takeover of his ship where defeating them was the number 1 concern as they were going to change time and convert the people of Earth into drones. He stops and explains to a women from the time period that they have moved beyond money....
In the tv show they came across people frozen from hundreds of years earlier and Picard was facing the destruction of outposts along the Romulan border (Borg) and they have a Romulan warship decloaking off their bow. Picard explains to a former rich investor that again they have moved on from money and we work to better ourselves....
Star Trek: The Next Generation can really be boring. I have read descriptions of episodes of it being like a meeting in a teachers lounge.
BTW Star Trek: STD is just that, a STD.
The actors and writers and studios involved in tv shows and movies always ask for more and more money. They never want to pay more in tax then they have to. Try taking the stuff these people have that they bought with their money.
