Has technology and finance changed what love and marriage are on a fundamental basis?

I know it's a heavy question but it's a fact that today most marriages don't end in death and according to the way the vows are written, this is a bad thing. Before, a certain co-dependency within a married couple gave them incentive to get through rough patches. Although marketing did exist before, it wasn't as present on our mobile phones and embedded in signature tones, smells, etc. telling us that this kernal of luxurious euphoric happiness should be ours in every aspect of life, including our marriage. My grandparents for example were more realistic "They could say I hate the person I love" and it somehow made sense and the love was there, sometimes more visible than other days but the marriage was rock solid. Have all of our fancy gadgets and financial independence killed this?
