We would all agree the world would be much nicer if we did not include selfishness and arrogance in our list of character traits. The "I am right and you are wrong" world view inevitably leads to global death and destruction. At the very least, it leads to an impasse in communication. But I like to think on a smaller scale, as you may have noticed, so I will now fill in the blank with things that are closer to home.
The world would be much nicer if___________:
...we didn't think women needed to be thin to be attractive. Or for that matter, we wouldn't think that women needed to be attractive at all. That way, we could all enjoy an occasional piece of cake and plenty of wine without feeling as though we were overindulging and doing something very very bad.
...I could have fluffy lemon pancakes every morning for breakfast without having to buy bigger clothes.
...we didn't make so many gender distinctions, so people could be people first and do their jobs and live day by day without having to jump through unnecessary hoops. And no one would ever have to cover their heads unless they really wanted to, and wives would never have to walk four steps behind husbands, unless they really wanted to. (I live near Amish world)
...we didn't get so worked up about money and being concerned with how much our neighbors earn and judging them for making too much or too little.
...the arts were as emphasized as math and science in school.
...there weren't quite so many rules governing our activities all day long, and the people in charge of enforcing them could be a little flexible. They could use phrases like "don't worry about it" and "go have yourself a nice day anyway," or "you're driving a little too fast. But that's OK. Try to watch out for the other drivers because the rules are really meant for them and not for you anyway," instead of "you're late to class. Here's a detention," or "you're late with your payment. Here's a penalty," or "you're driving a little too fast. Here's a ticket."
...parents never had to bury their children.
...appliances were made to last a life time instead of five or six years. Planned obsolescence would not be part of the manufacturing equation.
...we could each have three wishes granted in a life time, a chance to really dream big and make them count for something, and no fair wishing for more wishes.
Fill in the blank for yourself, and see what kind world you would create.
