Why was Martin Luther King so concerned by the issue of poverty in America?

The poverty rate was higher among African-Americans, more than the poverty rate of White people. This occurred because of the fact that White people did not like Black people as tenants, or did not sell their houses/homes to them. They thought they would not have the money to pay for them, and besides, the South was segregated at the time.

whose power in the senate is equal to the power of the speaker of the house?
