The Global economy relies a lot at exports.
And the tourism industry is one of those that are going to suffer the most if the borders are going to close. 1-2 years are already too much. There are so many countries that have a huge portion of their GDP based on the tourism sector.
the reason for reliance on imports and not making their own is political
governments charging licences/tarrifs/taxes for making locally. but awarding credits for not producing
take UK. when in the EU the UK was forced to limit its farming/fishing production because of EU quotas. where it would punish people for making more. but award farmers for not farming and instead doing other stuff.
if you owned farmland. that had a quota of 200 cattle. and you only had 10. you would get rewarded with 190 so that another farm can have more then their quota by paying the cost for the extra
these quota's are a currency in of itself. people buy(fined) or sell(rewarded) their quotas
this is all about not having abundant supply so that they can have an increased demand and cause commodities prices to rise.
its all about limiting production so that wall street can make profits.
its not about not having the physical lack of capability. there is enough land. there are enough unemployed people looking for a job. its just when a farmer earns less than the cost of rearing cows. and gets fined for raising more cows than allowed. but gets compensated if he has less cows than allowed. meaning he earns more for having less produce..
which is the cause of less local produce
the EU buys quotas so that the EU can produce more while the UK produces less
if farmers are allowed to just farm and produce as much meat as they like and sell it at the value of its cost. then farmers would not need to convert to 'airbnb' hospitality to survive. and grocery stores would not have to rely on imported meats
