It depends how much you think you have to earn in order to "keep your nose above water". Many small businesses do not earn much and so have no need or ability to "sprinkle", incorporate etc etc.. you will be unaffected by these changes that are meant to scoop up the wealthier self employed who are exploiting unintended loopholes aided by their accountants/lawyers. However the lobby against this move is intended to enrage all business owners in order to make it stronger.
