Internal contradictions of capital accumulation

When people talk about capital accumulation, they mean the process by which money (also known as capital) is saved, invested, and then used for making more money. Internal contradictions of capital accumulation happen when the things that help a business grow and make more money can also be the things that make it difficult or impossible for the business to succeed. For example, when a company expands, it has to hire more workers, but if the company doesn't have enough money to pay those workers, then it won't make money and could lose money instead. Another example is when a company increases the price of a product to make more profit, but that means it can lose customers who can no longer afford it.
