The article's use of $200K is very weird, and the top 1%-5% definitely make much more than that (and they don't depend on an annual income/salary). $200K after taxes is not that much, especially if you have a house, more than one car, children, student loan debt, want to save, etc. I don't know of anyone at $200K or even more to be involved in any sort of offshore tax shelters.
As for pass-through businesses: I had a pass-through LLC when I ran a consultancy. Was I engaged in tax evasion? I'm pretty sure I wasn't - as I understood, this was exactly what I was supposed to be doing.
Pass-through isn't tax evasion, but as an example opposite to yours, I used to know someone who created an LLC and then bought things as LLC expenses (like computers, printers, etc) that were really for personal use.
Edit: I have no idea how to quote text on HN
