I think Samoerai's number 10 on the list to help Indonesia get out of the middle-income trap has something to do with more productivity and better concentration after a good night's sleep. I'd prefer that the mosque speakers be used only for the adzan, but I am unsure if this will significantly increase GDP.
With all respect to Samoerai, I think some other items on his list will cause more harm than good. Allow me to elaborate.
1. Dua anak cukup.
I think this is not something the government should interfere with, it's a couple's choice to have no children, 1 or many. Besides that, capping at 2 kids max with a 15% infertility rate of couples, the population will shrink. And that will hurt the economy. A lot. With less consumption companies' stock market value will go down, aging population with no one to pay pensions and take care of the elderly. Japan, and Korea are already experiencing it. Some Western European countries escape this by net migration, but this has its pitfalls.
Rather, a growing population is good for the economy, and labor could become an export product of Indonesia to countries that are in dire need of workers (see the thread on nurses needed abroad)
6. Improved infrastructure is vital, but as we can see happening right now some of these investments are made with huge loans from foreign countries (China). This will make Indonesia vulnerable to their growing influence.
8. Banning fossil fuels in a poor country like Indonesia will lead to a complete economic standstill. Forbidding the affordable means of transportation while subsidizing the more expensive EV's will cause great inequality and division between rich and poor.
9. A social security system...will this create a better economy? Higher taxes that's for sure. Wages will have to go up to compete, and more inflation?
With number 2 I agree very much, education needs to be affordable and of good quality. It's a very important key to progress and development.
