There were several different restrictions placed on blacks due to the Jim Crow laws. The following are just a couple examples.
1) Poll taxes- This was a certain amount of money an individual would have to pay in order to vote. This negatively effected African-Americans, as many of them could not afford this tax.
2) Literacy tests- These were written tests that individuals had to pass in order to vote. These were extremely difficult to do well on, due to the wording of the question or the time given to complete the test. This targeted African-Americans, as many of them had no formal schooling as of this time period.
3) Segregated public facilities- Everything from public schools to public pools were segregated in order to keep blacks and whites away from each other.
B.) to leave alone and let be
Laissez-faire refers to a free market economic policy where the government has no control over the economy. It is a French term which means to "let it be".
Capitalism in its pure form is a laissez-faire economic system. During the late 19th century, the US practiced laissez-faire capitalism. The government had no regulations on the economic system and employers were allowed to run their businesses as they wished. In a free system like this there are opportunities to become very wealthy but workers are often exploited.
