If you don't, then you're not looking. Here's what it's like being a black United States Senator:

If this is happening to a United States Senator, what do you think it's like for an average black person?
A Stanford University study determined that black drivers are more likely to get pulled over by the police. The study compared the number of blacks being stopped during daylight, and the race of the driver could easily be seen, with the number of blacks being pulled over when it was dark, and the race of the driver could not be seen. The study found that a much higher number of blacks were being pulled over in daylight than when it was dark.

It is against the law to pass laws intentionally targeting people because of their race, which is why it isn't done. Instead, one political party targets poor people, of which a disproportionate number are people of color. One political party refuses to expand Medicaid in states they control, which is preventing many people of color from getting health insurance. One party wants to cut food assistance programs like WIC, which provides food and nutrition to poor women, children, and infants, of which a substantial number are people of color.
One of our political parties has also been making a massive effort to suppress the vote of people of color and disenfranchise them, especially in this past election, where they tried to get votes thrown away in four cities, of which a large number of the people living in those cities are people of color.
Nobody thinks that, but there are people who may need some help from government to get by, and liberals want to make sure people who do need help, get it, especially children. Our government has passed a number of laws to outlaw housing discrimination based on race, while Trump ran an entire campaign around keeping black people out of the suburbs.
You're assuming the people are at fault, rather than the system. If our government spent more money on education in poor areas, provided free childcare for single mothers, provided universal healthcare like every other western country, had a higher minimum wage, and a more fair criminal justice system; you would see far fewer single mothers living in poverty. This isn't just theoretical. In other western countries, where government does more to help single mothers, far fewer of them end up in poverty.
