A National Lottery To Select Our Legislature

Somehow, our representative government got away from representing us. If it does then we are a nation of Lawyers. Our founding fathers were Lawyers, Farmers, Businessmen and Clergy. But, today our Representatives are for the most part rich lawyers. I have to ask how does a lawyer know what Farmers need? How does a Lawyer know what Teachers need. If we got away from our current system of electing professional politicans (i.e. Lawyers) to our House of Representatives and went to a lottery system (much like drawing jurys from a voter pool) We would have a better cross section of our people representing us in the House. This would be similar to a grand jury, where people would serve a maximum of 2 years (maybe 1). We would have farmers, teachers, nurses, doctors, blue collar workers, military, businessmen and other fields who would serve accordingly representing their state.
