A good government does that by managing employment and skill flows. Trade colleges, paid apprenticeship etc, all go a long way to reducing downstream costs.Lol, that is basically all the govt should be doing outside of social investment (health, education etc). Expanding the productive capacity of the country. That is how you sustain economic growth.
Fucking hell, we have a housing shortage (incl social). We have a building sector tanking (builders will leave). If the govt wants to retain sector capacity it should increase it's build program to retain the workforce.
