Money is debt. If money is printed, make sure it goes into the production sector, not into the consumption sector or into the pockets of rich/corrupt people. Because if economic growth is calculated based on consumption, it means we expect inflation. That's the same as pouring gasoline on the fire. So, every country, if it wants its economy to grow, must protect the private sector and MSMEs with policies that favor farmers/traders/small producers.
Several sectors are needed for economic growth, not just one sector. In my opinion, economic growth depends on the category of the country in terms of its economy as well. If the country is classified as a developed country, maybe the economic growth sector only needs one or two sectors. If it is a developing country, the direction of policy to support economic growth should not focus on just one sector such as the production sector that you mentioned. At least several sectors need to be focused on. This is a sign of talking about corruption.
Honestly when you are a developed high level nation, like USA or UK or anything like that, you are free to care about a lot of things, because you have a budget to care about a lot of things. Otherwise there is nothing wrong with a developing nation to focus on just one thing, like if you are a poor nation, that puts all the money they can pour into technology, that would be enough because you do not have the budget to just keep on putting money into everything, you can't do that but you can pick something and right now technology is the best return on money.
This means that poorer nations needs to pick one industry to get great at, even if it is not technology, it can be something else and they can pour money and education for kids and all that for everyone, and then gradually they will become better and better at it, and the results will show. It is not one year or even five year plan, it is 20+ year plan, but in the end if you do it correctly then you make money from it as a nation.
