We have described economic growth as a function of increased worker productivity, and we have argued that increased levels of capital and technology have resulted in increased worker productivity. We have argued that the greater a country’s capital, the greater its ability to produce. This is true on a macro level, but it is also true on a micro level—that is, when we acquire machines that help us be productive, our individual productivity increases.

What machine(s) do you use every day to help you be more productive? Please be more specific.
What would you be unable to produce or do without this/these machine(s)? Would you have to give up some of your hobbies?
Can you think of any machines you could buy (and thus accumulate more capital) to help you produce more? Do you think you’ll see diminishing returns? If so, why or why not?
