This simply isn't true for ALL white people!
For instance, the second panel shows Bob's grandparents becoming home owners through a government subsidized mortgage loan. By contrast, my grandfather inherited his land from my great-grandfather received -- FREE OF CHARGE -- 160 acres of land stolen from the Lakota Sioux by the United States government.
That's right, the US Army drove-off the natives (not all of them, they killed a bunch too!) and then gave the land to my great-grandfather for NOTHING! And my family has been reaping the benefits ever since!
How'd I get a job as a kid? I worked on the farm that our family got FOR FREE! How did I finance college? By using that land as collateral for my loans! How do I make passive income from the big city? By renting that land and through the massive subsidies in the Farm Bill! What happens if there's a bad year? Government-backed insurance and price-subsidies see us through!
Has hard work played a role in our family's success? Oh hell, yes. But that hard work wouldn't have paid off the same without the unjust opportunity offered us by Homestead Act of 1862. And why did MY family get the opportunity live off the land? It was 'cause great-grandpa was a white dude in the right place at the right time!
So it's simply NOT FAIR to imply that all white folks have had the advantages of Bob in the cartoon -- some of us have had many, many more advantages!
