"Growth" as a substitute for willingness to pay for what you want, has been around for at lest 60 years. It is a prize example of "having your cake and eating it." I first came across it in the campaign for the 1964 election when the then Labour leader, Harold Wilson, assured us that the UK could build the New Jerusalem with a modern infrastructure, effective social services, vibrant local government, well financed health and education services, without it costing the voters a penny.
It would be financed out of growth.
Growth would be achieved by setting up a government planning department which would replace the uncertain progress achieved by hit and miss private enterprise.
Labour won the election and the Department of Economic Affairs under their Deputy Leader George Brown was set up as an antidote to Treasury staidness. Eventually the project was blown off course by "events."
Most developed economies had, however, achieved and continued to achieve substantial growth in the 30 years after 1945. The French called them "les Trente Glorieuses.". The most outstanding success was Germany. Most others achieved a modest annual average of around 3%. As R A Butler, an earlier Tory panjandrum, pointed out, this enabled us to "double our standard of living in 25 years."
However, from the mid 1970s such rates of growth became difficult to maintain. The backlog of the war years had been eliminated, new technology had been absorbed, the economies with lots of peasants (eg France) had transferred them to the more productive industrial sectors (the UK hadn't many peasants so used immigration from the Commonwealth instead) and the economies had matured.
Nevertheless the struggle for growth continued, largely becasue it seemed to be the essential to maintain full employment.
But for those who cared to look.the writing was on the wall from the early 70s The "Club of Rome " (unrelated to the EU, I believe) published "The Limits to Growth" which claimed that current rates of growth among the developed countries, with less developed countries catching up, would exhaust the planet's resources and make it uninhabitable through pollution. Their conclusion was; "Either civilisation or growth must end."
There have been many more recent and more readable accounts since. In particular I recommend:
