If it is true that...

Communism aims at abolishing the right of personally acquiring property as the fruit of one's own labour

and

Wage-labour does not create any property for the labourer but creates capital, a kind of property that exploits wage-labour

and

Capital is a collective product and a social power

and

The average price of wage-labour is the minimum wage that suffices to prolong and reproduce bare existence

Then it must be true that...

In bourgeois society, living labour is a means to increase accumulated labour while in communist society, accumulated labour is a means to promote existence of the labourer
