get rid of the other people, and who will buy their products? If the Capitalists cut out all the blue collar workers and only leave the top 10% employed, what consumer is going to be able to afford their products and/or services? Do they just do business with themselves, sell to other countries, or let the business rot away due to a lack of customers? If you create a nation of $5/hr wage-slaves flipping burgers, working as security guards, working as store clerks, etc they are not going to even be able to afford to own a home much less a car or two.
No, this economy and business needs middle-class workers to be able to keep business and the economy moving.
