What are you smoking? There are a lot of small businesses that don't even come close to generating a couple hundred thousand a year. The businesses that do generate $200k or more a year didn't do it overnight. It takes years and plenty of man hours. It's highly unlikely that you're going to open a small store and be an overnight success. It takes a long time, and this along with many other reasons is why most businesses fail.
We talking profit or revenue? I also have to admit that I don't have a universal rule for all businesses. If you have a labor intensive business like a low margin super market you will have to raise prices. No way around it. People want their customer service. So if you live in a place with $15/hr minimum wage you´ll have to pay more than $10 for a steak dinner at Applebees and your haircut isn´t going to cost $9 anymore. From my point of view though with small businesses it makes very little sense to go and start a business making $100,000 a year risking everything with my house on colateral and working all those hours when I can work for another company making that kind of money. Starting a business means I'm shooting much higher. Starting a business in a 3rd world country with a 8% tax liability still has a goal of 6 figures.
If you generate $200,000 in profit for yourself then that's great and sucking up a $100,000 in extra expendatures sucks. However you have to ask yourself why you need so much labor to generate that profit. I think the example above with supermarkets is a good example, just like with a hair salon, where costs will need to rise.
If I had to run a 6 man company to make $200,000 a year then I would seriously look at my margins and what´s going on. At some point you either have to raise your costs or start thinking about working for someone else. At that profit a bad year might wreck you. A couple bad deals. A lawsuit. Even if you win your lawyer fees will eat all your money. You´re out of business really fast. Like I said, with the amount of risk you need a lot of reward.
This is not my personal choice either. I wish that lots of mom and pop stores still existed but the days of working on these tiny margins are kinda over in most industries. Huge companies come in and work on economies of scale.
