I am no expert in economics or the medical field but I wish to express my thought on the current pandemic and the global economy.
The world cannot go on the way it is. Closing one's border is not a practical way. It can caused the world's economy to collapse and hurt millions around the world. Covid-19 will not kill as many people as a dysfunctional economy can. Poverty and hunger can kill many and suicide is not excluded.
The world is interdepend on one another. Tourism and related activities are important to the survival of many. Therefore, my suggestion is to open the borders and allow people to travel. It will not only boost the airline and tourism industries but the world trade as well.
For a start, all countries should allow Covid vaccinated people from other countries to enter without restriction. Sure, the visitors should observe some protocols like wearing of masks, social distancing etc.
We are not sure how long more this pandemic would last but it has been a year. What will happen if it goes on for another one, two or maybe five more years? Are the borders going to be closed for that long?
