Today is different to the past, people in the sixties thought that jobs would be there forever, today we live in a time when nothing seems to last, what does the future hold for those working today, will they be working until they are seventy, will they have enough money to survive in their old age, what will a government pension be like, will they have enough in their super.
Money we need to provide for our family as best as we can, then we also need money for our old age, money is extremely important. As for being "worth", one has to make their own worth, make themselves invaluable to their employers, head down arse up, do your job efficiently and look after your money.
