the reality is bad things happen sooner or later and this attitude banks entirely on linear growth. the bigger you are the harder you fall, so if you're hiring employees without knowing whether you can afford them or not, then that's just wreckless and shouldn't be praised or encouraged.
it's almost an 'all or nothing' approach where you reinvest everything you earn indefinitely because you want the snowball to keep growing. sooner or later, the snowball will start melting or you'll have to push it uphill and this philosophy will have to be 'put right' by sensible people who only spend what they know they can afford.
it's a bit like playing the lottery and the guy that wins is giving advice to those who want to win - "play every week, buy as much as you can, that was my secret"... yeah, well that will work for some people, but for most people it won't work.
