He did prove one thing, and that is that rich people legitimately think anyone who has less money than they do is just lazy. Even in the face of overwhelming evidence to the contrary and his own failure the article seems to imply that he still thinks that is the case lol guess he didn't learn anything at all...
Worse, he thinks he was just unlucky that he happened to get sick, and thinks his "success" proves he was right all along. Meanwhile, his "success" was entirely built on leeching off other people and abusing charity.
The sad part is that he couldn't put two and two together. Health problem interrupting your job? It's not like poor people ever have to deal with health problems, they're just lazy, right? /s
