During the 19th century, the average child in the rural US had exposure to a few dozen people before they turned 18. Of these children, those whose parents took education seriously in the home, by age 14, had better skills in fundamentals such as reading, writing, mathematics, history, and applied science than the average college graduate today. Lockdowns and masks, while evil, have limited effect on child development when you engage in a small, relatively autonomous community, such as a local church of under 100 people, and homeschool your kids rather than handing them off to the NEA gulags for eight hours a day.
