Social costs
A society often pays an excessive price for economic growth in the form of environmental pollution, eroding social/ cultural values, compassion.
Inflation
The injection of new money by governments to favor economic growth leads to inflation/ currency devaluation, which disproportionately affects the poor, for the following reason.
The poor spend a greater fraction of their income on food/ raw materials, whereas rich tend to spend a greater fraction of their wealth on services. During inflation, the price of commodities grows at a much greater rate than the price of services.
Growth imbalance
Thus, with growth, the monetary imbalance between the rich and the poor tends to grow.
