They seem to think that single people have more time than the others to pioneer.
The truth is, singles have LESS free time, because they have to work full time to support themselves AND prepare their own meals, do their own laundry and other chores. Married brothers come home and have a hot meal waiting on the table, then they study while the wife does the dishes, and washes and irons his clothes. Both husband and wife can share in household chores and yardwork. A single person has to come home, cook his/her own meal, do his own laundry and ironing and shopping and cleaning and all other household chores.
They also seem to think single people are lonely and depressed, sitting around crying about not having a mate.
And, of course, they think the cure for loneliness and depression is to go out in service.
