Use modern communications technology to keep senators and representatives in their district. Keeping these folks out of Washington would keep their physically away from a lot of the lobbyists who would actually have to travel the country to see the reps.
Having the reps living and working at their professions in their districts would allow us to dispense with their salaries and benefits as reps would be earning their livelihood in their own professions, eye doctor, lawyer, used car sales, bartender, instead of being on the public dole.
The reps should NOT be working on their professions in their districts. Being an elected representative of the House or Senate is a full time job, not something you can do on even a part time basis. You've had a part time President for the past 4 years and NOTHING got done. It's going to take a lot of people working full time, overtime, and all the time, to set things right again.
Also, being a member of a House and the Senate requires you to discuss, interact, and working in concert with your fellow House Members or Senators. You cannot discuss, debate, or otherwise negotiate with your fellow members from your home district. Legislation involves gathering information on a lot of stuff you know little about, learning about them and making decisions. It involved interaction, discussion and education, which as we have learned from attempts to teach school children, is not effectively done via the internet.
Your post indicates that you think government does nothing. You have never come across as one of the more well educated or astute posters but the level of ignorance in suggesting such a thing shows how little you truly know.
If you owned a company with assets, income and expenses in the trillions of dollars, and hundreds of divisions and thousands of subsiduaries, would YOU want a bunch of part time executives who were more focussed on their own companies and profits, running your company, to do you want these random people to learn how your company works, and what it needs, and the best way to keep it operating.
Stop acting like government is just politics - it's not. Government is the what keeps property records and protects individual property rights, through the patent and trade mark system. It's what provides the legal framework to incorporate businesses, hold property, invest, build, invent, and to enjoy and retain the fruits of your labour and your investment.
