Yes, if you are wealthy and live on a high tech world. But Traveller Tech Level is defined as the maximum level an economy can sustain with a population of 10 ^ TL. So 10 people, even with books of knowledge will be at TL:1 bronce age within a few generations. 100 people at iron age and so on till Tl:8 is our current knowledge, its not 9 because most parts of population does is to poor and not yet educated to participate in the economy. And Tl:9 of course offers the first future techs, e.g. fusion reactors. Tl:A reliable interstellar travel and automatic factories, and huge progress in the high times of big trade empires spanning years of FTL travel, and the collapse of civilization, technology and dark ages, when ever those empires fall. Living at Tl:F and being wealthy could buy you a lot of years, before you need to worry about age. But I was restricting my idea of a "better" assignment to Tl:8. So you can imagine every career path here and now, e.g. odd ones you never want to live in real life like the doctor who works for crime syndicate (above example), but that is fun in a role playing game, or would make a good trope in a novel or film.
