In poor countries childhood mortality is higher than in developed countries, so that if a couple want to have two children, they need to give birth to more than that, as there is a strong likelihod that they won't all reach 5 years of age.
Also, as a country develops, the average income rises and people don't need to have so many children to help raise food, fetch and carry water, etc. etc. and support their parents in their old age.
they have so many kids because they want to get money for them from the government

As the population ages, there will be a smaller proportion of people of working age who are supporting those that are too old to work. In many Western countries with low birth rates, this has pushed back the age at which people can retire. Furthermore, many countries had a state pension system under which some of the tax paid by today's workers went towards the pensions of those that are retired. Low birth rates results in a increase in the dependency ratio: there is an increasing number of retired people depending on each worker.Furthermore, if the birth rate falls below the replacement rate, the population will gradually die out.

There are too many factors to take into consideration before this question can be answered successfully. The first issue is the size of the company.
