This is very true. There are an enormous amount of different visa's the US have available to people wishing to stay in the US on a permanent or semi permanent basis. This is the reason that almost all job ads state "must have authority to live/work in the US", as you have stated, HR people have no clue about visa's and the various requirements nor do they want to sift through piles of documentation to determine eligibility.
The only reason the E3 has been an easy way for us Aussies is because someone worked out a few years ago the low cost, ease of acquiring and almost unlimited renewal was perfect for airlines.
