Capital is not THINGS as much as THINGS INVESTED TO PRODUCE MORE THINGS. This can be represented by the famous M-C-M' equation.
The Bourgeois/Captialist are those who invest Capital( goods, information, money, services, equipment) and get MORE IN RETURN.
The Proletariat are those who's investments (Labor, time, money, etc) return less or break even. Their life energy is skimmed off to increase the Bourgeois return .
By this definition, both the lower and middle classes in this country are Proletariat.
The best way for the Bourgeois to redender the Proletariat impotent is to divide it into the Working and Middle classes. The middle class is able to live fairly well, concidering it is trapped in endless work and acruing credit debt. Because the middle class beleives that the situation isn't that bad, it tends to blame the worklower class for not working "hard enought." Likewise, the lower class veiws the middle class as Bourgeois.
This division keeps the Bourgeois out of the spotlight. They are able to craft economic policy, speculate not only in goods and services but also in financial markets. Just please remember that it is those who control the MEANS OF PRODUCTION who are on the other side of class conflict.
