We define growth as the expansion of wealth in society; growth is about generating a "a bigger pie".

Amidst debates over the merits of continued growth, we begin with the idea that all else equal, a society with growth, with more wealth, is preferable to one with less. Without growth, society becomes a zero-sum distributional game: anyone's gain is another's loss. Growth (all else equal) enables shared prosperity.

But there is broad agreement that current measures of growth, such as GDP, are inadequate to the task of providing a suitable proxy to guide further growth. Whether devising revised measures, such as Tyler Cowen's notion of wealth plus" (GDP, plus measures of leisure time, household production, and environmental considerations), or constructing altogether new proxies (OECD's 'Better Life Index), the conversation about how best to measure, and thus drive, equitable, regenerative, socially desirable growth is a rich field of debate.
