Population and Man power resource is always an asset and not a liability, in the time of war the nation with the most people will always win as a larger population can be replaced easily without the slowing of the economy and industry for a longer period of time, it only becomes a liability when we fail to use it to it's full potential.
Lets look at this way there are almost 200 million Pakistanis today, imagine that only a measly 2% of the total population become developers, that would be around 4 million developers in total, imagine the billions of dollars of money they would be making through freelance and other software house/factory work each year, Pakistan would literally become the software hub of the world, other nations like Kazakhstan, Australia, European countries, Iran etc which are bigger in land mass than Pakistan but not even a third in population cannot even hope to reach such levels and that's the reason why we have the potential to be a real power house of the world if we put our mind to it.
