If you want to get serious answers, you should ask your question in a less biased way. For example, "What are some significant contributions to society by black people over the years."
Also, the fact that illiteracy, criminality, and welfare tend to be higher in black people has little to do with their race. Those three things are more common in lower income areas, no matter what a persons race is. There are countless studies around the socioeconomic factors that keep poor people poor, any why black people are more commonly poor, but that is a whole 'nother conversation.
Black people have made countless contributions, more than there is room to list, but I will name a few.
Otis Boykin invented an improved electrical resistor used in computers - radios - television sets and a variety of electronic devices. Boykin's resistor helped reduce the cost of those products.
Charles Brooks invented a street sweeper truck and patented it on March 17, 1896. Historically, prior to Brooks' truck, streets were commonly cleaned by walking workers, picking up by hand or broom, or by horse-drawn machines. He also patented an early paper punch, also called a ticket punch
Benjamin Banneker was a scientist, astronomer, inventor, and writer who created the first American built striking clock, invented the first Farmers' Almanac. In 1753, he built the first watch made in America, a wooden pocket watch. Twenty years later, Banneker began making astronomical calculations that enabled him to successfully forecast a 1789 solar eclipse. His estimate, made well in advance of the celestial event, contradicted predictions of better-known mathematicians and astronomers.
Agricultural chemist, George Washington Carver invented three hundred uses for peanuts and hundreds more uses for soybeans, pecans and sweet potatoes. Countless products we enjoy today come to us by the way of Carver.
George Carruthers led the team that invented the far ultraviolet camera spectrograph. He developed the first moon-based space observatory, an ultraviolet camera that was carried to the moon by Apollo 16 astronauts in 1972. The camera was positioned on the moon's surface and allowed researchers to examine the Earth's atmosphere for concentrations of pollutants.
John Christian was working as an Air Force, Materials Research, Engineer, when he invented and patented new lubricants, used in high flying aircraft and NASA space missions. They were used in the helicoptor fuel lines, astronaut's back-pack life support systems, and in the four-wheel drive of the "moon-buggy".
Charles Drew made discoveries relating to the preservation of blood. By separating the liquid red blood cells from the near solid plasma and freezing the two separately, he found that blood could be preserved and reconstituted at a later date.
Mark Dean and his co-inventor Dennis Moeller created a microcomputer system with bus control means for peripheral processing devices. Their invention paved the way for the growth in the information technology industry.
Dr. Daniel Hale Williams was a pioneer in heart surgery, performing the first one in 1893.
Philip Emeagwali won the prestigious Gordon Bell Prize for his work with massively parallel computers. He programmed the Connection Machine to compute a world record 3.1 billion calculations per second using 65,536 processors to simulate oil reservoirs.
Fred McKinley Jones was one of the most prolific Black inventors ever. Jones patented more than sixty inventions, however, he is best known for inventing an automatic refrigeration system for long-haul trucks in 1935 (a roof-mounted cooling device).
Seargant Adolphus Samms - 1958-1967 - Invented various systems for space travel including:
Parachute release mechanism
Rocket engine pump feed system
Air frame center support (eliminates need for second and third stage engines)
Multiple stage rocket
Air breathing booster
Emergency release for extraction chute mechanism
Rocket motor fuel feed system
