The best thing you can do is form an investment club type of thing and then talk to your investment buddies about investing in a local business. Explain how investing in a local business is better for the community as a whole compared to investing in opportunities that are based in other states or even other countries. Show how keeping the money, both investment and profit in circulation in your country is much more helpful to the economy than spreading it to places not even associated with your community and who are not giving something directly back to that community.
In case no one has noticed there are less and less American based and owned manufacturing businesses today. The market is wide open for interested parties to open these type of businesses and produce products for those of us who want to keep our currency in this economy rather than bleeding it dry.
