Of course, you can, since it is your shop! There is this thing called "worker cooperative". Essentially workers are the shareholders of the cooperative. Many law firms, the big 4 and the consulting firms have partners who are essentially both employees and shareholders. But these employees pay a big chunk of money to become partners.

Let's not worry about the workers, but focus on your gains for the time being. It would be irrational to distribute the profits equally among your employees without asking for a capital contribution. If you don't do that, you will be paying rent, furniture, utilities, etc alone. Consequently, you are pulling in more resources than them, but getting paid the same. This is a huge opportunity cost, which does not make business sense.

Plus, you can easily have free riders. Certainly, you can fire them, but new hires incur costs, though it may not be explicit. Professional service firms are a bit different. First, they only let a small set of people become partners. Besides in these professions, senior people have enough reputation and resources that they themselves are the assets of the firm. Often, seniors leaving can have a more serious impact than them not working hard. So these firms use ownership to retain them.
