CHunone dar bolo zikr namudem, sababi harakati odamon bayni bozori mehnati sohahoi gunogun va dar on jo tagyir yoftani sathi muzdi mehnat vazi tamini molho dar bozor meboshad, ki in yo on korkhona istehsol mekunad. Tanosubi talabot va taklifot dar bozori mehnat, ki muzdi mehnatro muayyan menamoyad, mahz az hamin vobastagi dorad.
Binobar in farqiyat dar pardokht va sharoithoi mehnat bayni shirkathoi muvaffaq va shirkathoe, ki davrahoi dushvorro az sar meguzaronand, unsuri hatmii bozori mehnat meboshad.
Vale agar muzdi mehnat tanho bo chunin tagyiroti kutohmuddat dar vaziyati bozori chen karda shavad, pas, dar nihoyati kor dar hamai sohaho va kasbho darajai on ba sababi harakati kadrho az yak korkhona ba korkhonai digar az payi pardokhti nisbatan balandtari mehnat takhminan yakrang khohad shud.
Farqiyat dar pardokhti muzdi mehnat ba panj omili asosi vobastagi
dorad:
Murakkabii mehnat. Vazifahoi mehnati har qadar murakkab boshand, onhoro hamon qadar beshtar omukhtan lozim ast. Baroi on ki odamon ba in rozi shavand, kushishhoi ilovagiashonro bo muzdi mehnati nisbatan balandtar jubron kardan zarur meboshad. Dar aksari mamla
kathoi mutaraqqii jahon odamoni sohibi tahsiloti oli, chun qoida, nazar ba onhoe, ki korashon chunin tahsilotro taqozo namekunad, muzdi mehnati balandtar megirand va in qonunist, zero odamoni sohibi tahsilot ba bozor bo donishhoi mukammal va malakahoi ziyod meoyand. In imkoniyat medihad, ki onho baroi kiroyagirandagon namudhoi nisba
tan purarzishi korro ijro namoyad. Onho baroi hajmi kaloni sarmoyai insoni, ki ba ikhtiyori kiroyagirandagon vomeguzorand, pardokhti beshta
re talab mekunand;
Vazninii mehnat. Baze korgaron nazar ba muhandison muzdi mehnati beshtar megirand. In vobasta ba on ast, ki muzdi mehnat boyad ba onho na tanho ba kushishhoi omuzishi ikhtisos doda shavad, inchunin vazninii ziyodi korro dar baze namudhoi istehsolot jubron namoyad.
Mahz ba hamin sabab muzdi mehnati korgaroni sanoati metallurgi va
khimiyavi, inchunin angishtkanon, odatan khele baland ast;
Mahdudiyati istedodho. Dar tamomi jahon maoshi varzishgaroni varzida, musiqichiyoni rok, saroyandagoni nomii opera, sitorahoi kino khele baland ast. Har kadome az chunin odamon bo sababi istedodi favqulodai tabii doshtan dar bozori mehnat chun «moli nodir» arzish
dorand. «Haridoron»-i chunin molho boshand, khele ziyodand. Ba tavri di
gar guem, bo vujudi ziyod budani talabot, peshnihodi chunin «molho» baso mahdud ast. Bo in sabab narkhi chunin istedod, yane pardokhti mehnati u ham to khele baland ast;
Darajai khavfnoki, ki ijroi in yo on kor ba on vobasta ast. Havfi kori baroi jamiyat zaruri har qadar baland boshad, odamoni baroi ijroi on rozishuda hamon qadar muzdi mehnati balandtarro baroi on talab mekunand. Inro az jumla dar pardokhti mehnati kormandoni ikhtisoshoe, misli angishtkan, havonavard (lyotchik) – ozmoishgar, kayhonnavard, sohibkoron va mutakhassison oid ba amaliyoti birjavi (masalan, bo kogazhoi qimatnok) mushohida kardan mumkin ast: in jo yake bo salomati va hayoti khud tavakkal mekunad, digare bo mablaghoi hangufti puli, ki ba miyon guzoshta shudaast;
Siyosati ijtimoii davlat. Agar mekhanizmhoi iqtisodii mamlakat mutadil kor kunand, bozori mehnat bo farqiyathoi ziyod dar sathi pardokhti muzdi mehnat baroi odamoni kasbhoi ommavi roh namedihad.
