So here I go: in 50 years, I predict that the world economy is likely (though not guaranteed) to be thriving, with global GDP growing by as much as 20% per year, and income and consumption doubling every four years or so.
Por isso, aqui vai: daqui a 50 anos, prevejo que a economia estará provavelmente (mas sem certeza absoluta) a prosperar, com o PIB global a crescer tanto quanto 20% ao ano, e com o rendimento e o consumo a duplicarem todos os quatro anos.
