A fairly standard lesson in economic theory today but rarely spoken in the mainstream is Milton Friedmans NAIRU . the Natural rate of unemployment. Though the theory is prize winning and complex like most stuff in economics its actually really simple hidden in jargon. There is level of unemployment inthe economy 'required' to keep prices..and thus wages..stable..if you have to low unemployment inflation will occur. Most people still beleive the goverment actually seeks to give everyone a job but this has long since been abondened in light of this 'theory' Basically speaking the way your employes out there can ensure your wage is kept a certain level is by knowing if you quit someone else is willing to take your job for that wage..if noone was willing to do so..you coudl ask for more money. In the same way today we see that immigrants though often blamed for economic failings crime etc are widely encouraged to enter the labour market in order to ensure a constant supply of people willing to accept very low wages. In light of globaisation and now the mobility of companies to travel overseas at limited cost they now have access to ecnomically viable cheap sources of labour to do almost any job. So how can any governement today realistically expect to reduce unemployment without reducing real wages of its people.. and in the long term do we just have to accept we 'need' unemployed and desperate people to keep our system stable.
