This is the problem with capitalism: As people become more efficient at their work, they should be able to work less time for the same pay. Instead, it is the capital which benefits - the business owners, the profit takers. As people become more efficient at their work, companies hire fewer people. This means more people looking for work, which puts a downward pressure on wages. Additionally, people are told they can succeed if they just “work hard”. Nowadays, with mobile phones and computers, people are expected to be always available, effectively working longer hours, meaning companies can hire even fewer people. More downward pressure on wages.
This is the problem with our society. Fifty years ago, if an employer had told his employees he wanted them to work 60 hours for the same pay as working 40 hours, so that the employer could hire fewer people and make more profit, the idea would have been risible. Society would not have stood for it. Today, society has been convinced that working 60 hours for the same pay is not only expected, it is viewed as morally virtuous. Being exploited by business owners so they can make greater profit is seen as a moral duty - people who refuse or complain about this are seen as “lazy” and “entitled”.
As a society we need to change this. If people can do the same work in 20 hours that it used to take them 40 hours to do, they should be able to work 20 hours for the same pay, not forced to work 60 hours for less pay.
