Let's take a moment and reflect on how intricate of a government that the United States if America has today.  It seems like an impossible task to configure the blueprints of this democracy like the founding fathers did. They had no roadmap, since the last great democracy happened in Greece.  All they knew was what they didn't want their government to be like.  They knew they didn't want a king, and they didn't want the government to have the ability to levy ridiculous taxes.  Now after they scrapped their rough draft know as the Articles of Confederation, they created a functional government which could protect its citizens and be productive.  Throughout the next 2 and a half centuries, our government has evolved into a more modern style where politicians go to school to learn how to argue their political point and the military representatives in congress are reducing in percentage.  However, America is still based off of the constitution which was implemented roughly 2.5 centuries ago.  It has made its way through numerous recessions and one Great Depression.  It will always be there, and will always be difficult to change because it is hard to argue with something that has lasted so long.
