How is he getting those?

Look: Search "Adobe Photoshop CS6 Windows 32/64 Bit – Official Software Download & Serial Key" on eBay, I can't post links.

So much money from doing probably nothing.

How did he get those serials? I've also seen somebody selling Windows activation keys, but those he stated he get from broken PC's probably from the electronic waste site. He gets so much money he can pay some and get access to go there every day.
