Starting your own business should not be the best or only vehicle to prosperity. You should be able to make a comfortable living working a normal job that doesn’t break you.
Failure rate of small business is high, and you can’t blame all of that on lack of startup capital. Bad concept, bad execution, bad location, etc. could all play into it. The taxpayer should not be obliged to keep a “quirky” store running if it doesn’t bring in customers. Throwing good money after bad isn’t going to bring prosperity to anyone in the end.
Not to mention that they compete with each other, not just the megacorps. I’m pretty sure there are half a dozen hair salons on our main street alone, and most of them sit empty at any given time, endlessly changing hands. Incentivizing startups will only make competition more fierce, so a few more winners but much more losers.
We don’t need more restaurants giving the community more below minimum wage jobs that can’t be filled. We need that money helping everyone, with rent or groceries or something, so that they can actually have money to spend at the small businesses that exist.
