its a very good point, but i think that nower days its not because of the educational / industrial or intelligence level of different that makes the different its the fact that back in the day our families had respect and dedication now days it is o too easy to find and easy girl, and i think the most successful relationships these days are the ones that both parties are working, and respect each other everyone needs there independents and there own rights to live there life how they see and feel fit, so its not down to ''success & progress by education, careers,investments, financed, cars etc.''
