Earlier quoted context omitted.
The guy applied for an investor's visa. He's not an investor. If your wife applied for an investor's visa and not an I'm-married-to-an-American visa and didn't get it and said, "But I really love my husband." that wouldn't mean that she'd been unfairly denied.
And what other people and I are saying is that the whole system is quite fucked up and needs a major overhaul. Maybe this guy shouldn't have got in on this particular visa, but it's still lame; I'd much rather people like that have the option to go, and then get encouraged to go home if things aren't working out, or some similar compromise that encourages smart, hard working people to go to the US.
I definitely agree that the US immigration system is pretty broken, but assuming that the US system was fixed, and there were still different kinds of visas, it wouldn't magically be broken again because people got denied for applying for the wrong kind.
