...say black people were only spendinginvesting money into lack businesses. with the same amount of money generated as there is right now, the gains of only spending money in black owned/ operated/ran businesses would be:
1)increased awareness of what industries are lacking in the black community, and thus money would be directed towards those venues. RESULT: even more black owned businesses providing the things that we used to look elsewhere for
2)endless circulation of money WITHIN the community. banks and other finacial institutions would have their profits going towards the community instead of away. RESULT: beginnings of self-sustained system
3)economic and political influence within the larger arena of this nation and abroad. interests of the community and voices that would otherwise be go unheard would be recognized.
Notice that with this idea, which could very well be in place now, economic policy will shape naturally. ideas are the driving force behind moeny, always.
