If you get the same answer from one or more people with stats to back it up, it has to be true. Some of the most prominent people (CEO's, executives, etc.) have one thing in common: They're married. Common sense would tell you that the higher you go in your career, the more responsibility you'll have. Look at President Obama: US President, husband & father. Taking care of a family is one thing, but being the US President is another. The President has to do what's best for the entire country, even if some people won't agree with his decisions. Michelle seems to do a very good of holding it down with him, even though she's got her own initiatives going on. If there's ever a time where a helper is most needed, it's when you're tasked with running a country and your family. Will there ever be a single US President? Probably not, but it could happen. In the eyes of public opinion, if you're not married then you're not stable, and to me that's ridiculous.
I'd like to see a single US President one day, because (s)he could show the public that a single person can be just as, if not more responsible than a married person. Think about it: A single US President could devote more time to their job because their responsibility would be to the country. At times, a single US President would feel overwhelmed because of how much is on his or her plate; (s)he would have to shoulder the burdens alone. The more responsibility you have, the greater need for help so I understand where a supportive spouse would come in. Prominent people have a lot of responsibility so I understand why they're married; their spouses can carry some of the load. I think it's crazy to assume that singles aren't capable of high-level positions because of marital status. If anything, I think a single person is better suited for a high-level position because they can devote more time to their career. They don't have the responsibility of juggling work & family.
