Most economists think infinite growth in a finite world is a good idea. Companies reinvesting in themselves and growing bigger is not inherently a good thing.

Large corporations, in my opinion, are already causing the breakdown of local societies. Deals are done over large areas, less and less people are in control of their own fates. More and more externalities are caused as business leaders are more detached from the realities of their actions. Wages for workers are lower as more needs to be paid to management, and profits get used for stock-buybacks rather than bonuses and higher wages, to please shareholders rather than workers
