Not a country's but let's say in one city. If one seller fails to deliver good products, you can sell better ones and take their customers. There is no space in the economy for soft hearted because everything is a competition. You have to compete for resources. You have to compete for demand. You have to compete for customers.
The fact is that the sky is big enough for every and anybody to dwell together without necessarily being at a log ahead with one another. if as a company or firm you are able to build your brand in such a manner that it speaks for itself, you do not need to expect another brand to fail just because you want to see yours doing well.
Even when you look at it from the angle of different nations thriving to be be more relevant, you still have to recognize the fact that every nation has areas where they are good in. some might be Agriculture, others might just be oil and gas, some medical and others might be tech. without seeing yourself as though you are competing against any nation, a nation can concentrate on building her natural resource and focusing just on her strength. that way, it becomes you fighting against yourself and not waiting to take advantage on the weakness of any other nation.
