What does the gift from FAO schwartz represent to the girls?

He (father) always brings surprise presents for the girls from F.A.O. Schwarz, and this year has brought each of them a cast-iron mechanical bank for holding pennies. Sandra’s bank is a girl who jumps rope when a penny is inserted, Yolanda’s is a bank of Jonah and the whale, and Carla’s bank is a figure of the Virgin Mary ascending to Heaven. I think all these gifts represent the materialism of America. There are Biblical connotations to as well. Carla's bank, in particular, seems to say that if you put money in the bank, the Virgin will somehow ascend to heaven and grant her material desires.
