I think it is beneficial that items like cars, foods, clothes and furniture that are produced in a certain part of the world are now available almost everywhere, which means the similarities between different countries are growing.
One of the reasons is that many people in various countries now have an opportunity to operate products which they could not use before. There are several goods that are produced in the certain parts of the world, which means that other country people could not normally utilize them in the past. For example, some fruits as bananas and pineapples are grown in tropical countries and so, some colder regions like Russia and Canada did not use these kind of fruits. Although, most people in such countries are now able to buy and consume these beneficial fruits.
In addition, people today can travel to different countries for study, work or live without less fear of becoming homesick since the products are used to are now available in shops almost wherever they go. For instance, Iranian immigrants could not cook their national food in other parts of the globe because the specific vegetables which required for meal were not farmed and grown in most other countries in the past. However, they have a chance to purchase all these ingredients in shops and supermarkets around the world today, and they can work and live more productively because they do not miss their cultural heritage anymore.
In conclusion, I believe that the growing similarity between various countries around the world is a desirable and positive development. People can take advantage of beneficial items from other countries, and immigrants can be less stressful and more productive.
