Economic reasons for wars in the capitalist era?

The vast majority of wars in the capitalist era began and were fought for several main reasons:

Due to the desire to own sales markets
The need to own colonies
For spheres of influence

Every capitalist developed (assumes the presence of a well-developed industry) country needs to have markets where products can be freely sold. As a rule, these markets were precisely the colonies or less developed countries.

In the colonies, the capitalist state placed branches of its companies and, at the expense of cheap labor, achieved enormous surplus profits.

The problem was that the number of colonies was limited. As a result, wars began. The best examples would be: World War I and World War II.

Such a policy is called imperialist, which takes place in modern conditions.
