I'm sorry but this is a misinterpretation of the degrowth thesis. The proponents behind degrowth (i.e Hickels, Kallis) are constantly correcting this misinterpretation. Degrowth stipulates that the global south actually needs to continue to grow to reach important indicators associated to the quality of life of their citizens.
According to them, the actual "degrowth" has to happen in the global north where economies are over-saturated [0]:
> We live in a world where poverty remains and those with unmet needs require more resources to satisfy them. We also live in an ecologically-constrained world struggling to cut emissions as fast as possible. In that context, by reducing consumption in the global North (and more generally for all of those who are over-consuming), one could free some of these resources for the people who need it the most. Ensuring basic needs and well-being for all necessarily implies limiting consumption in high-income regions and wealthy households in order to enable resource-poor countries and households to reach decent standards of living. In other words, degrowth in the global North is a prerequisite for sustainable development in the global South.
