Simple math.
Husband is a deadbeat. Wife makes all the bling. 0+1 = 1.
Husband makes all the money. Wife spends all the $$. 1+0 = 1.
Husband and wife both work very hard 1+1 = 2.
If you cannot understand this then

A wife cannot make a man powerful if the man is did not have the potential to begin with. Likewise, a man cannot make a woman powerful if she did not have the potential to begin with. With each other, there can be synergy thus 1+1 > 2...at least that's the idea.
