Based on an economic perspective, large national debt affects the economic growth negatively. It is almost impossible for a government or country rather to sustaining a large and growing national debt. Some of the effects come from the side of investors who begin doubting the possibility of the federal government to continue servicing the economy and government spending (Boubekar et al., 2016). There are three major effects of large national debts on a country’s economic growth. First, large debt draws money away from nati Why the US should not close the Mexican Border onal investments which would earn then government some revenues. This is due to lack of enough money for the government to service effective investments. This would mean that the government is heavily spending, but there are minimal or no revenues being generated hence lack of capital to be reinvested. There will be no growth in the country’s economy. Secondly, large debts negatively influence taxation and spending by the government. This is because when the country is suffering from high national debts, all the attention are focused on what the government can do to continue sustaining itself. This is where the government adjusts. As Boubaker et al. (2016) put it when taxation is high workers and investors are negatively affected by tax increment and Why the US should not close the Mexican Border  can be left with little or no money to reinvest. Also, the tax increment leads to economic downturn from the side of the policymakers and investors. Policymakers find it challenging designing policies on tax spending in an environment where there is an extremely high national debt. The economic growth is normally hard in such a situation based on the fact that there are no sufficient funds to fund any new challenges that arise along the policy-making and policy implementation processes.>
