Men can rationalize buying a $30,000 boat after saving $100,000 by building a house and putting a lot of sweat into it. Blood, sweat, tendonitis, scars, etc.

Women can rationalize buying an $8,000 ring and a $35,000 mid sized SUV because she's been keeping things together at home while the man has been working 100+ hours a week, and thinks she's earned it. She's also been working on chastity and the size of her butt.
