Answer:
To stop segregation and for everyone to have civil rights including african americans
Free African Americans were allowed to hold low paid jobs during the 1840s and 1850s.
Explanation:
Slavery prevailed during the period of 1840s and 1850s. Though African Americans were freed after the emancipation proclamation, there were black codes that were establish which curtailed the opportunities for the African Americans to hold highly paid jobs.
Though they were skilled craftsmen and artisans, they were considers to be professional rivals against the whites and hence they were given low paid jobs. They were employed as barbers, but many blacks when denied jobs had opened gambling houses and started to earn in an illegal manner. They were also working in laundry and many were paddlers.
If checks and balances didn't exist, there would be nothing stopping a group i.e. the president, from making whatever laws they wanted.
In essence, if there are no checks and balances, government is no longer a democracy because nothing prevents the group in power from doing what they want. For example, a president that wasn't checked by the opposition party could pass a law saying that they are legally allowed to be president until they die, and nobody would stop them.
