Yep, a small company with a capitalization of Cr70,000,000, a board of directors and perhaps 1,000 stockholders. The company's chief asset is 1 Far Trader Starship, One of the player characters would be chairman of the board and also the ship's captain, the other players are members of the board of directors and also the ship's crew. The stockholders determine who the board of directors are. So long as profits are made and dividends paid out the stockholders are happy.Or characters can be employed by a rich patron/small corp. By the way, it could be very realistic for a character to begins with loads of money, as long as he's got a *REALLY* good explanation, like having SOC 18+ (ie: being Daddy's Girl helps a lot if Daddy's a Duke)
Well, the expense of starships and the high cost of space travel guarantee that space travel is uncommon in the OTU, unlike Star Wars where there are cheap starships. The typical Traveller character stays on his planet most of the time. Traveling to a different planet costs about Cr4,000 in low berth or about $12,000 for us. More expensive than air travel. typically one can travel to another star system or buy a new ground car. For the price of a brand new home in Westchester, NY ($700,000), you can charter a starship for 2 weeks, and travel to the star system of your choice that is 1 jump away.Well, playing retired characters can be fun if you're not retireing the character from adventure. Also, by definition of every Traveller game systems, it is impossible to survive while doing "Only Legal Trading", meaning the PCs really NEED to go out the beaten path and take risks. Forcing the Characters to find something to have ends meet is one of the basic Traveller Idea. Nobody's interested in playing "Cubicles and Bureaucrats" or "Broker, Distributors and Salesman"
This explains why there are different tech levels at different worlds. Importing items from offworld is expensive so most goods are produced locally. Only high value goods are profitably transported from system to system.
