"بازارهای رقابتی سودها را از بین می‌برند"

Simplified Meaning:

In places where many businesses compete to sell the same kind of product, it's hard for any one of them to make a lot of money. For example, think about how many coffee shops there are in a big city. Each one tries to attract customers by lowering prices or offering better deals. This means no one coffee shop can charge a lot without losing customers to others. Over time, the prices get lower and lower because everyone is trying to get an edge. So, while customers benefit from lower prices and more choices, businesses end up making less profit. If you're starting a new business, it's important to know this because entering a crowded market might not make you a lot of money. Instead, finding a unique product or service with less competition can be more profitable.
