Is America's cultural influence positive or negative?

I believe that America's cultural influence plays positive role in our society. I’d like to talk about why I think so by using two points.

First, food culture. Especially fast food or dining out. We can expect to reduce burden for cooking. Recently, women have played important roles in our society and they pursue their own carrier. They don't have leeway to cook after work. In this case, dining out is effective to reduce their burden. For example, my wife has her own job. She is up to her neck. Therefore, I don't want to impose a burden on her to cook dinner after work. We usually go out dining when we have meal together. I believe dining out helps us to generate leeway in our life.

Second, logical thinking. In globalize world, logical argument and direct debate are inevitable. Japanese tend to use common phrase such as “We will try to think about this matter positively.” It includes ambiguity and it could cause procrastination in some cases. Even Engineers who need logical thinking, they lack convincing data for argument. For example, some of my subordinates try to design our semiconductor micro chip for cell phone without any reason. I always chastise them. On the contrary, westerners demand clear ground/evidence. They set exact time/due date. I believe that this is good aspect Japanese should follow western’s example.

In conclusion, America's cultural influence is significant in our society. I believe that it has positive influence.
