Growth is perhaps the most important metric in the modern economy, but it is a very bad measure of economic and social performance for many reasons. More does not mean better. Quality has value as well as quantity. In a shortage environment more does mean better, but that does not hold when there are endemic surpluses. A more does not mean better when there are constraints such as those that are posed by environmental issues. The system is complex and better metrics are needed in order to get the best possible results.
