It is possible to be optimistic about the short term and pessimistic about the long term
Some observers are surprised that certain economists are optimistic about the economic outlook for OECD countries, while others are pessimistic and are announcing a crisis. Why this apparent contradiction? Perhaps because it is possible to legitimately be : Optimistic about the short-term outlook for OECD countries, as the expansionary fiscal and monetary policies are prolonging the growth period; Pessimistic about the long-term outlook for these countries, given the rise of financial imbalances (public debt, asset price bubbles, holding of bond portfolios at very low interest rates, misallocation of savings, etc.).
