It's not easy to work from home and devote as much time and concentration as you would in the office. Some people can do it, some people can't. From experience, I can tell you that when you "work from home" your relatives assume you're simply "at home" and load you with errands as if you weren't working at all. The ability of working from home allows you to do work for a company that is a few states away, but you will still need to be present at the office a few times a year for most employers. Tete-a-tete communication will never be replaced by the internet. It's simply not the same. Whoever says they've got true friends whom they've never seen are lying to themselves, lol. In order to keep relations you must be physically present a few times a year. Our country has how many people living in it? Add to that the thousands from abroad that are here as tourists/visiting relatives/business people. I went to Europe twice this year, so I was in one of those green dots four times. We are all raving about how the world got smaller, how distant places and people got closer to us, but we're forgetting that the most important factor in achieving this are cheap plane tickets and not the inet. Train can only carry you so far in a short amount of time. Sure, if you're going from NJ to California you're still in the same country, but you have to consider the distance. To compare, imagine our states are like the little countries of Europe. You can drive to the neighboring "country", and the "country" beyond that one, but anything further than that is strenuous and time-consuming even by train. Even for traveling inside cities, you have to consider the distance. Big cities have well-developed public transportation, but smaller ones don't. The nearest grocery store might be miles away even in Staten Island, NY; suburbs must be worse. You see, an average family living anywhere outside the very center of a big city can't function without at least two cars. Bigger airplanes are the way to solve the problem, along with alternative, less polluting fuel.
