It's in the country's best interest to have a thriving economy; making it easy to start a business supports this concept. The whole idea of throwing up obstacles to weed people out smacks to me of elitism. Starting a business is difficult enough without adding more rules, fees, licenses, etc that have
nothing to do with the business's day to day operations.
Just look at countries where you need to have $thousands in escrow/bank before you can even get off the ground and compare how many small businesses they have to the US.
I mean, really, if I wanted to start a business tomorrow I could do so without filing a single piece of paper as long as I did it under my own name. As long as I'm not in a regulated field, all the gov't cares is that I pay my taxes. It doesn't get any easier than that!
