One of the foundations of MRP is working to increase SMV so as to be above that of your wife's. In general, Men's SMV will increase over time as their career progresses (as long as they stay in good shape both mentally and physically) and a woman's will decrease as her beauty fades. When the point is reached where the SMVs "cross" doesn't that inevitably lead to the man being dissatisfied?
For those of you who have reached this point (and if you say that your SMV has always been higher than your wife's, sucks for you) how do you deal with this imbalance in the other direction? Isn't the temptation to "trade in" for a newer model constant?
