I understand their positive impact on GDP and employment, but we should also understand that, when the competitive advantage is one-sided, benefits will diminish and, in the worst case, could even be negative.
Compreendo o seu impacto positivo sobre o PIB e o emprego, mas deveríamos também compreender que, quando as vantagens competitivas são unilaterais, os benefícios serão menores e, no pior dos casos, podem até ser negativos.
