In the video below, Kevin O'Leary does a pretty good job of explaining how many regulations disproportionately adversely impact small businesses relative to large businesses.
My only quibble is that he keeps referring to job creation and taxes paid to state and federal governments as benefits of successful business. Those are not benefits — they are costs of doing business. What I would have liked to have heard is how much these businesses improve our lives and how excessive and inefficient regulation prevents companies from doing this. Creating value for others is the sole purpose of a business, not creating jobs or paying taxes. If that's what O'Leary thinks is the benefit of starting a business, then I have a company to pitch him. We simply create jobs by making stuff and then destroying it all.
Even still, kudos to Mr. O'Leary for defending capitalism.
