I also was exposed intentionally along with my brothers, and I think there is a capitalist critique in there somewhere.

When one of us got the Pox, the kids had to stay home to prevent spread. This requires a parent or other child support to accomplish, which requires time and/or money that is uncompensated by the Capitalist. If each infection happened individually, that would mean a week or so is needed to take off work and/or child support per infection. Thus exposing all the kids meant that time was overlapped in a way that minimized the time workers (particularly women) were away from the workplace and thus could earn wages. It is yet another way families are exploited for the wealth of Capitalists.
