Majority of policies, rules and regulations are imposed for a whole economy without paying attentions to different residential sectors. As a result predicted growth may not be attainable. Even predicted growth is attained it is not sustainable.
There is no such a thing as context-based or residential-based or localized policy when it comes to national development or economic policy, hence, "national" policy. It would be considered both waste and favoritism to aim national policy conditioned on context.
National economic policy, if done correctly, are both attainable and sustainable. How? Elect good, competent, and ethical (honest) representatives to govern your country.
I think you might be asking two kinds of questions here. First, you don't seem to clearly articulate your definition of "growth." If you are saying GDP, then you are using a macro-measure of growth to look at localized subeconomies. It is well documented that GDP is a poor indicator of localized micro-economies due to its aggregate nature. So, first define how you are measuring growth, then either attack the measurement or policies that target GDP.
I have said whole economy. It is macro economy. I admit per capta GDP is a poor indicator. But development economy built upon this poor indicator. Whole economy is scattered into regions, societal cultures, and institutions.
Applying single policy to cover all the contexts does work. That is my main argument.
