Dear Always,
In our times, employment is about earning salary in a trained position.
In earlier times, one used his physical skills to create what was needed.
Like milking a goat or growing vegetables.
So today it’s more like the kollel guy who does the shopping and fills the car with gas.
There are not so many that can always be found be their gemara.
Those guys earn the support they get. (If they get.)
And that genre is centuries old.
