i wonder if it would have been possible for single families to exploit the "one child" culture later on by having a lot of children, thus providing much needed brides and grooms and profiting from the wealth gained by marriage. sure, this would have been a long-term investment and might have lowered you social standing in the beginning, but there'd also be pressure for the others to marry your kid to other protestants (even if those are less wealthy) than to outside catholics.
