What effects? The more workers the better. We should also then send out a larger number of people overseas to counteract the influence of the large Indian diaspora.
Of course top notch education is also a must.
Its not for nothing the Prophet (saw) said he wants us to have many kids so he can be proud of our numbers.
I hope one day we overtake India's population.
This is insane. Please educate yourself on these matters before wishing a demographic bomb upon your countrymen.
Overpopulation stretches natural resources, stretches government's resources and fiscal spending per head, meaning worse education, healthcare, infrastructure spending per Pakistani. Already we're competing for water resources, arable land, and electricity. A high population growth rate undermines and worsens all of those things.
It also cuts at economic growth, if we grow 2% of the economy per year and 2% inflation and 2% population growth. That means real GDP per capita growth is actually negative. Over population also causes land, housing and space issues, slums come with overpopulation. Unemployment will also be made worse, sure we have more people in the labour force, but not enough aggregate demand or investment to make up for it, so unemployment.
Pollution, and environmental effects of having too many people is also quite clear. Right now, South Asia has some of the most polluted cities in the world, and you wish to make it worse? There are also indicators from studies and actual date that shows overpopulation correlated with higher crime rates, and lower life expectancy.
For the love of God, think about these things before advocating them.
It's a terrible idea.
