This is true, if you view "helping" someone as throwing money/whatever at them. It's that act that takes away the incentive to work, as i'll be addressing later on... In my mind, it's disrespectful to throw money at someone. It insinuates that they can't make it on their own, which is insulting.
I have two responses to this
A. People have tried and failed to start businesses for years, through all of history. And really, is the problem actually solved by giving people a handout? A better way to decrease the risk of your business failing would be decreasing your losses. We Need Tax Reform.
B. What's to stop them from getting employed? Why do they have to "start a business"?
For point 3: see my "A" response.
For point 4: "more willing"... maybe, but we really need to see evidence that they actually do if that claim holds any weight whatsoever.
and... IsayedGIT is on point.
