In the US, there's a great deal of protectionism that really makes it difficult for your average person to start a random electrical business. You usually need 4+ years of experience as a licensed journeyman. That requires 4-5 years of apprenticeship school and usually 2-3 years as a helper before you will be able to get in. No chance at that "startup" until you're in your 30s usually. Next, you need a few hundred for the exam. You need thousands in "working capital". Then you need tens of thousands for a bond. Not many people have that kind of money lying around. Finally, as a final dose of nepotism, you have to be "pre-approved" to take the exam. That means that a few people who already have master's licenses must approve you to become their competitor.
