It's true that once the economy is over a very difficult period such as a crisis, reducing government intervention tends to have positive impacts. One can think of government interventions that are necessary in times of crisis, such as in 2008-09 or the current crisis. It's not unthinkable to imagine a world where we return to the pre-crisis level of government spending and that unleashes economic growth because of the sad economic downturn that took place.
It's not surprising to me that in the 1990s, where we had poor economic prospects, the country was deemed an honorary member of the third world by The Wall Street Journal. Governments took action to change the mood and instill confidence by reducing spending and ensuring that the finances were on a more sustainable path. It led to increased investments and economic growth. That's very often what happens.
