Can women make the world a better place?

I’m a guy. In the end, everything I do is for women. For example, I eat so I will be healthy so I will be desirable to a woman. I clean up so I’ll look good and be desirable to a woman. I studied in school so I would get good grades, land a good job so I would be desirable to a woman. You get the idea. (I’m not on the market since I have a great woman now. Sorry.)
Here’s my thought. Women can change the world if they dated (and mated) with certain guys. For example, if our society needs to conserve fuel and be more ecoolgically sound, women can start the rumor that guys who drive Hummers all have short bits and are making up for it. If women only dated guys that drove small cars most single guys would be fighting to drive SMART cars.
The idea can be applied to other areas. If women recognized that guys who wear “Bling” are money wasters and avoided them, it would only take a short a while before men stopped getting gold caps.
If women only dated (and mated) with men who were polite and respectful, the loud, rude and crude would either change or die off without procreating.
Do you believe women can change the world by being more selective about whom they date?
