Infinite growth is possible and it is what our societies aim for. But, in its deepest, it is a pseudo-growth, because prices rise, but eventually salaries must eventually rise again to match the prices.. So, in the end, everything gets back to the same relative levels!

I concur, it is what developing economies strive for and what developed(sic) economies strive to maintain. Anything is possible, it is the methodology that provides the results(good & bad). This philosophy has been the acme of societal success since blood-letting was believed to be a cure all & the earth was thought to be the center of the universe. The tangible reality is, higher & higher margins are required to achieve that growth. Whether this is achieved by tech, innovation, exploitation or inflation is moot, what is certain is always more has it's costs & limits.

That isn't growth -- real increase in wealth, as Adam Smith defines it ("the annual labour and produce of the Nation"), or as mismeasured to a lesser degree by GNP / GDP -- but monetary inflation.

Some research finds that growth has limits: https://en.m.wikipedia.org/wiki/The_Limits_to_Growth
