The work has changed a lot over the last 100 years.

The technology has made the new works are very different than the works in the past.

For example the agriculture is one of this work that has change a lot, at the beginning of the last century there aren’t machines as tractors or others and it was necessary a lot of people to cultivate the land but currently there is necessary only one person, just like the work in factories; nowadays, there are robots and computers which make the work of a big number of workers.

In spite of this the humans are necessary in the factories.

Consequently there are social changes and working conditions.

In the future the most demand jobs will be associating with the healthcare because of the ageing of population, moreover there is a problem with this ageing population and this is that if the people live longer there won’t be enough money for the retirement.

In conclusion, it is necessary a review of the jobs and the system for paying the pensions.
