Some of these, especially Valentine's day, could also be labeled "commercial" but I guess that's the nature of capitalism to commercialize any kind of festivities.
Tbf, Valentine's Day, Mother's Day, and Father's Day at least were created specifically by Hallmark to sell cards. So they were created as capitalistic commercial scams...
Valentine's Day was originally a celebration of Saint Valentine. Like Christmas, it got rolled under the capitalist machine until the modern holiday became completely unrecognizable from its roots.
