Which is required for the standard living to go up?

The amount of a worker or employee’s wage. If that employee or worker is earning enough then at least he or she is making ends meet. If the person’s wage increases, it improves that person’s living standards because they can now afford better things or save up for future plans when the need arises.

For the standard of living to go up, one needs a functional economy which can produce a lot of goods and enable a functioning and free-flowing economy where people can buy and sell their things. This enables everyone to have more things which eventually can lead to a higher standard of living.
