▁real ised ▁by ▁them ▁will ▁typically ▁diver ge ▁( with in ▁certain ▁limits ): ▁enter pr ises ▁can ▁get ▁more ▁or ▁less ▁income ▁for ▁the ▁value ▁of ▁what ▁they ▁produce . ▁That ▁diver gence ▁becomes ▁a ▁critical ▁factor ▁in ▁capital ist ▁competition ▁and ▁the ▁dynamics ▁of ▁the ▁production ▁system , ▁under ▁conditions ▁where ▁the ▁average ▁price - level s ▁for ▁products ▁are ▁beyond ▁anyone ' s ▁control . ▁ ▁Compet ition ▁between ▁produ cers ▁If ▁capital ▁accum ulation ▁becomes ▁the ▁dominant ▁mot ive ▁for ▁production , ▁then ▁produ cers ▁will ▁do ▁everything ▁they ▁can ▁to ▁cut ▁costs , ▁increase ▁sales ▁and ▁increase ▁prof its . ▁Since ▁they ▁mostly ▁lack ▁control ▁over ▁the ▁r uling ▁market ▁prices ▁for ▁their ▁inputs ▁and ▁outputs , ▁they ▁try ▁to ▁increase ▁product ivity ▁by ▁every ▁means ▁at ▁their ▁dispos al ▁and ▁maxim ise ▁sur plus ▁labour . ▁Because ▁the ▁lower ▁the ▁unit - cost s ▁of ▁goods ▁produced ▁by ▁an ▁enter prise , ▁the ▁greater ▁the ▁margin ▁will ▁be ▁between ▁its ▁own ▁cost - pr ices ▁and ▁the ▁r uling ▁sale ▁prices ▁for ▁those ▁goods ▁in ▁the ▁market , ▁and ▁therefore ▁the ▁larger ▁the ▁prof its ▁that ▁can ▁be ▁real ised ▁as ▁result ▁when ▁goods ▁are ▁sold . ▁Produ cers ▁thus ▁become ▁very ▁concerned ▁with ▁the ▁value ▁added ▁in ▁what ▁they ▁produce , ▁which ▁depends ▁cru cially ▁on ▁product ivity . ▁ ▁In ▁the ▁classical ▁compet itive ▁situation , ▁capital ists ▁basically ▁aim ▁to ▁employ ▁workers ▁to : ▁ ▁produce ▁and ▁sell ▁a ▁greater ▁volume ▁of ▁products ▁more
