Sometimes people have to examine history to know that they are not being fed. Back in the day, if you asked black people, who grew up poor, if they knew they were poor, many would say no. Because everyone lived the same way. You have to know it's wrong to want to right and history can help with that.
You're right there will always be racist and people will truly benefit when they can stop undercutting each other, while other watch us squabble over the scraps.
