It depends who's in charge of the nation though, you can have people planning for the long term well being of their population, or people planning for the next election cycle and making sure they amass as much power and money in the meantime.

That's the difference between planning nuclear reactors that will be built after your term, and used after your death, vs selling your national industries to foreigners, your ports to china, &c. to make a quick buck and insure a comfy retirement plan for you and your family.
