oh god!!!......what an interesting topic. upperclass/haves/rich people seem to oppose the love relationship due to a number of reasons
1)they are the one who have most to lose and they are the ones targeted by the gold diggers and have nots(how many times have you come across a man/woman whose only ambition is to snare a rich spouse by hook or crook so that they can lead life in luxury....i can assure you many.)even in traditional romantic sagas one of the leads is always filthy rich...i have always wondered why there are very few books on two have nots falling in love and working towards a glorious future(probably because love does not seem so rosy when you are dealing with harsh side of life)
2)with money comes power and it is a great high. one seems to forget humility with it , so it comes as no surprise that upper crust acts a bit snobbish.
3) there are practical issues related to adjustments , blood lines, and merger of interests . while most of new generation discounts or ignore these issues, they are bigger and more important than most people realise .
4) the upper class gets blamed because they are the focus of almost all shows, also people like to take a shot at them (blame it on human envy). the truth is that people from all walks of life and all financial status oppose love marraige depending on some solid reason. if you can believe , when i was in india my maid had disowned her daughter bcoz she married a guy not approved by her parents. eventually the marraige fell apart(the daughter was left fending a child and working around the clock, while her rickshaw puller husband was busy getting drunk, beating her and running after another women) and my maid would quote day and night how she foresaw(practical reasons) it and wanted so save her daughter from this life. even kapoors(karishma kapoor) did nor approve a love match between them and bachans(both are famous, have great bloodlines and are more or less compatible). i belong to middle class but even i would weigh love very carefully against practicality before i agree to a love match in my family.parents tend to agree to love easily is a myth(pick any culture , any class, any race, any religion)......most of them carefully analyse the situation before agreeing to it.i have seen a large number of love affairs around me but i have yet to come across a love marraige that was not initially opposed by parents and with good reasons most of the time.
