Are you suggesting his privilege wrote his software for him? Much less had the vision to start a software company in the 1970s - which his parents thought was a bad idea. They did not like the idea of him dropping out, he did it anyway. Paul Allen didn't come from any kind of privilege. So is the theory that he should be robbed of his amazing success and effort also, by association with Gates' association with his fa…
