It's a fairly simple matter for a person (particularly a self employed person or any person conducting anything other than straight wage earning) to incorporate. There are a number of disadvantages to this now if you earn less than about double the average wage. This should remove all of the disadvantages for most people and allow them to reduce their effective tax rate to only a few percent at most (Arianna Huffington style). It should also provide a tremendous boost for accountants, lawyers, etc. to handle the details. Laywers in particular, I think, as they would be setting up the corporations and giving advice on how to make best legal use of them. Accountants would also get a big boost although many people would probably elect to do their own accounting via computer accounting programs.
