Contraceptive Mentality Clear in New Homes

I just spent the afternoon with my mom and brother looking at some new model homes that opened in Irvine. It deeply saddened me to see how present the contraceptive mentality is in this area. The houses had for the most part 3 very small bedrooms and one huge master bedroom. I turned to my brother and said "obviously these builders do not plan for anymore to have more than 3 kids." Yes kids can share rooms but these rooms were so small it would be tough to get two beds in there. $700-900,000 and only enough room for a small family?? As someone who would embrace as many kids as God would bless me with I better start brushing up on my house building skills...
