There is a growing similarity among countries due to unification of products choice in the whole world. In my perspective, it is a negative development as it reduce revenues on tourism and affects local businesses.
First and foremost, possibility to buy the same products in any part of the world has lead to significant profit losses in particular countries. In the past, people had to travel across the world to buy a specific item, or to eat a genuine traditional dish. However, with globalisation, people can enjoy everything not moving far from their own place of residence. Consequently, the most popular countries among tourists experience a substantial decrease in budget income from tourism. As an illustration, earlier, people had to spend hours travelling to Japan in order to try their famous sushi, which were made exclusively by japanese chefs. On the contrary, nowadays, almost every town in the world has its own sushi bar, so there is no need to go thousands miles so as to enjoy fresh-made food.
In addition, while large international organisations are gradually expanding and making more and more income, small local business are suffering from profit losses. Mass manufacturing makes products cheaper that encourage people to prefer buying them rather than more expensive crafted alternatives. For instance, visiting a supermarket, I noticed that all the bottles of milk made by a popular international company was sold out. Instead, there was still a great choice of local brands, that were twice as expensive.
To conclude, incrasing similarity of products on a global scale is a negative development, because both countries and tiny businesses are suffering from profit losses.
