True, but I believe also its important to factor in that those in lower socioeconomic classes effectively have their time stolen from them in many ways.
ex: I don't enjoy fixing the vast majority of things I have to fix, (although there can be a sense of satisfaction in it sometimes), but I have to 1st learn to do so and then do it because I absolutely need it fixed, but don't have the funds to pay to have it done. To compound the loss of time, financially wealthy people can afford to buy new things, like automobiles, which dont break down or require nearly as much maintenance.
Many other things are also outsourced by people because their time is too valuable to do otherwise this outsourcing is just not an option for others.
