A system of economy based on continuous growth and limited resources is simply not viable. That is nothing new, the Club of Rome presented their findings already in 1970s.

Their conclusion was a rapid and uncontrollable decline in population and industrial capacity, and the signs of that would be apparent by 2072.

Given that the "business as usual" scenario has persisted, we are on track to that sudden crash "overshoot" scenario. In addition, now there is the looming climate catastrophy as well. Countries and regions have to become more resilient to all kinds of impacts from climate change, as it does not look like we can avoid or prevent it.

In addition, another economic system than one expecting continuous growth is required.

Therefore the question of "who pays for the reduction in growth" is a rather non-starter, as the reduction in growth is inevitable.

Edit: crash not at 2072, signs visible at 2072.
