Will they survive?

Since beginning our last assignment, I have been wondering how the colonization of worlds would work, specifically for the  medievalist. Historically, the colonizers do not typically build up a new society without the use of some “worker” group being forced to do a lot of the hard labor. Likely there’d be less of a caste system on this new planet that they inhabit and most people would be equal so how would they assign the people hard jobs? Without the use of robots it’s really hard to say how long this civilization will really last. Surely, it will be disproportionately lacking technological resources when compared to the other countries. It seems as though they have a lot of ideas of how society would be better without robots but personally, I think creating a new planet without them will be extremely difficult, if not impossible.
