The stimulus was meant to get us to 2%. When it hit hit 5.5% and 5% (both well above the 2% you claim it never rose above), it was pulled back on to not overheat the economy. trump said that stimulus would propel us above 2%, not realizing that is a very bad idea. His stimulus was not only a bad idea, but it failed. It led to almost all the major corporations being nearly technical bankrupt at once. We entered a recession at the worst possible time, a month before Covid-19 hit. It has been a complete disaster.
Obama reduced unemployment by record amounts to near record lows. This especially helped the blacks you claim were not helped. trump reduced unemployment a bit more, but it was impossible for him to do as much as Obama.
Obama had success. It was not the wildly great success some might have hoped for, but it was solid calm success. trump promised wildly great success, but instead he has delivered some of the worst failure ever.
