In the US... because it has a very weak welfare state and weak , a lot of workers... couldn't take sick leave if they were ill, because if they don't… - Ha-Joon Chang

<nowiki>[</nowiki>Modern monetary theory or Keynesian economic policies...] I'm not a macroeconomist but... those kinds of macroeconomic thinking will become more influential. I wouldn't say dominant because... the current macroeconomic approach [is] a weird mixture of... fiscal conservatives and monetary abandon ...dominant because it serves the powerful interests, so I don't know whether ...the rise of Keynesianism or the monetary theory—which is... certain—will be sufficient to replace the existing [system]... [It is] not just in terms of macroeconomic policy I mentioned that is going to see change. ...[W]e are going to see big changes in the way that we... manage the welfare state, which has implications for taxation policy. ...We are going to see big changes in the structure of production, which will has ramifications for and trade policy. So... it will be in all kinds of areas and hopefully... it will also spill into our approach to fighting . So... it's not just going to be in the macroeconomic area that the conventional wisdom and prevailing orthodoxy are being hit. It's across all areas, reflecting partly the all-encompassing nature about this crisis. So... there will be significant changes, but... whether one economic theory becomes dominant, or at least widely accepted, is in big part a political question. So a lot will depend on how things unfold and how the political elite respond to this.

[W]e are talking about a huge crisis... It's been all encompassing because in other crises usually there's one bit of the economy that goes wrong... Oil prices go up, collapses and so on, but this time... it's everything. It's about demand... production... the financial market... global supply chain... [A]s a result... the changes that we had to make... the kind of policies that governments have introduced to deal with this have been very very different and comprehensive compared to previous comparable crises.

Markets have a strong tendency to reinforce the status quo. The free market dictates that countries stick to what they are already good at. Stated bluntly, this means that poor countries are supposed to continue with their current engagement in low-productivity activities. But their engagement in those activities is exactly what makes them poor. If they want to leave poverty behind, they have to defy the market and do the more difficult things that bring them higher incomes—there are no two ways about it.
