While there will be less variety in what consumers can spend their disposable income on, capitalism will not collapse. Businesses will. In the age of technology, capitalism is diverse enough that some businesses will thrive--like those online--while others will not--like shopping centers. The businesses that thrive will need more employees to keep up with the growth. So, while in the short term there may be more unemployment, the free market will allow businesses to hire new employees and diversify. Capitalism will help itself recover from these circumstances, so there will be no need for another type of economic system.
