Ethics and investment
Peer to peer lending such as Kiva, Lending Club, Funding Circle(small business), SoFi(student loans), Prosper, and various other services provide you with access to the 'basic form' of investing you described in your question.  Other funds: You may find the documentary '97% Owned' fascinating as it provides an overview of the monetary system of England, with parallels to US, showing only 3% of money supply is used in exchange of goods and services, 97% is engaged in some form of speculation.   If speculative activities are of concern, you may need to denounce many forms of currency. Lastly, be careful of taking the term addiction too lightly and deeming something unethical too quickly.  You may be surprised to learn there are many people like yourself working at 'unethical' companies changing them within.
