The aim and motivation for the passing of equity crowdfunding was primarily to open up a new gateway of capital for small businesses, who are responsible for generating  65% of the net new jobs over the past 17 years in the US. Secondarily, the goal was to even out the playing field for wealth creation by allowing everyone, despite net worth or income, to invest in high growth potential startups at early stages, as opposed to only getting access to the Twitters and Facebooks of the world when the companies do an Initial Public Offering (IPO), at which point the majority of the hyper growth already occurred.
