Uhh..not always. The work is balanced out, but often, there is a net loss of jobs. There may always be a need for mundane labor, but that doesn't mean it will be priced at a point that makes living very sustainable. And no, technology doesn't necessarily make sustenance cheaper -- perhaps in theory but not in practice. Technology, like any other kind of a driver of industrial development, frequently concentrates power in the hands of those who can take it. Sometimes, that happens in a way that does make it such that more people can live better on less. It also sometimes happens in a way that blots out much of China's skyline with dangerous smog.

The ability for people to be able to live well, on the whole, is something that depends on society. Technology is merely a lever, not an autonomous agent or operator.
