The Shulchan Aruch Orach Chaim Siman 460:2 rules that it is proper for every Jew to take an active part in the baking of the Matzos for use on Pesach.
Amongst the reasons for this, the Mishna Berura(in S"K 7) quotes the words of the holy Arizal that "Getting 'into it' and sweating during the baking of the Matzos is a Tikun (spiritual remedy) for the "great sin" i.e. Hotza'as Zera L'Vatalah".
