How has the world changes since you were a child? Are these changes good or bad?

Since I was a child, the world has changed a lot. When I was a little kid, I would be able to go and wait for my dad to get off of the plane right by the gate. Now days, you can't even go up to the food court unless you have a boarding pass. Since 9-11 you can't even take your normal bottle of hairspray. Anything you take has to be less than 3 ounces. I understand that this is for safety reasons but why do they have to limit everything you bring? When I was younger, gas was under two dollars a gallon. Now days, your lucky to see gas go under 2.50 a gallon. Highway 99 is now under construction that will totally change the highway. Soon Chico will get to be like Sacramento. I mean it is already growing and undergoing changes to make it more like Sacramento. When I was younger, I didn't have to worry about my personal belongings getting damaged. Today, there are a lot of little punk kids that think its cool to smash in car windows or break into people's houses. The world is changing constantly. Some of the changes are for the better like airport safety, but a lot of the changes are not for the better. I don't understand why some things are happening. Is it really necessary to make the prices of everything outrageous so that living becomes almost impossible? I don't think so. I don't think that minimum wage needed to go up because that just means that everything else will go up too. People are struggling with money now days then ever before!
