Too much power to the central government.
Checks and Balances was designed to keep each branch from assuming too much power. Presidential power is checked and balanced in many ways. While he can veto various bills and keep them from becoming laws, he can be overridden by a 2/3 vote in both houses. SO if the Congress feels like the President is over stepping his bounds then they can in turn overrule him. The Supreme Court is also in the mix in that if they deem a law to be unconstitutional then they can rule it so and the law is no more. Presidents can influence Supreme Courts by whom they nominate for open positions (or in the case of one President, attempt to add more judges to the Court). However, after the nomination is made and the Senate approves and confirms them then they are free. The only way a Judge can be removed is they are found to be doing something illegal, deemed incompetent and unable to continue doing their job, resign, or die. This allows judges to "operate outside the realm of politics." The idea is that they can focus and not worry about politics and we can assume that decisions will be made free from political influences and bribery.
It depends on what time period you are referencing with African immigrants. Back in the 1500s, African people came to the Americas because of Slave Trade, but later on, they came to the United States under their own free will. Slave Trade forced African people on ships into the Americas, in which they stayed as slaves or did forced labor in a harsh system.
In the 1900s and later on, African immigrants came to America to seek asylum or safety in the United States because of problems going on in their countries. For example, in Rwanda, in the 1990s, there was some major problems going on such as genocide (mass killing of people) and some people came over to America to escape these hardships.
Also, another way they are different would be their culture that they brought. Their influence of music and African culture was very different as compared to other cultures from Europe.
<span>In 1903 the Wright brothers built the first powered airplane. They flew their test flight in Kitty Hawk NC, launching from the nearby sand dunes. Their first flight lasted less than 1 minute, but it still qualifies as the first powered flight by humans.</span>
