And if, as I said, it was necessary that the people of Israel should be captive so as to make manifest the ability of Moses; that the Persians should be oppressed by the Medes so as to discover the greatness of the soul of Cyrus; and that the Athenians should be dispersed to illustrate the capabilities of Theseus: then at the present time, in order to discover the virtue of an Italian spirit, it was necessary that Italy should be reduced to the extremity that she is now in, that she should be more enslaved than the Hebrews, more oppressed than the Persians, more scattered than the Athenians; without head, without order, beaten, despoiled, torn, overrun; and to have endured every kind of desolation.
A milestone for research on gender is the use of meta-analysis, which provides a way to assess patterns in a systematic way, which is especially relevant for a topic such as gender, which can be difficult to quantify. Nature and nurture have historically been analyzed when looking at gender in play, as well as reinforcement by peers and parents of typical gender roles and consequently, gender play. Toy companies have often promoted the segregation by gender in toys because it enables them to customize the same toy for each gender, which ultimately doubles their revenue. For example, Legos added more colors to certain sets of toys in the 1990s, including colors commonly attributed to girls such as lavender.
There have also been issues of toy safety regarding lead paint. Some toy factories, when projects become too large for them to handle, outsource production to other less known factories, often in other countries. Recently, there were some in China that America had to send back. The subcontractors may not be watched as closely and sometimes use improper manufacturing methods. The U.S. government, along with mass market stores, is now moving towards requiring companies to submit their products to testing before they end up on shelves.
