It feels like we are headed towards a caste based employment system in the West
I know the title may come off as strong but let me explain myself.
What I am trying to say is that given how difficult it is to find employment in the past couple of years, and with no signs of things getting better, the optimal strategy may be to work a similar job as some or most of your family members.
The reason why a young professional would want to work a similar job as their family members, even if they are not necessarily passionate about that particular line of work, is because they would benefit from multiple strong referrals or direct job placements.
I think over the course of a few generations, this will lead to families converging to having most members working within the same broad field, like finance, law, medicine, engineering, blue collar work and so on.
Young professionals that will seek out work that is detached from what their family is doing or have a family that does not have similar professions amongst themselves will find themselves in a difficult situation in terms of career prospects.
I also think this will impact how relationships will form once this thinking goes mainstream. People will start looking for partners that work in a similar field and try to ensure that the potential partner has family members that work within that profession.
