Another important point: Why would you expect the percentage of workers in low-skilled, low-wage jobs hasn't moved? Most of those jobs are consequences of the population; construction (housing and office buildings), maintenance/janitorial work or service industry (waitstaff, fast food), cashiers and other small business type jobs. Having a lot of tech jobs doesn't suddenly make those other jobs pay better, or require more skills... or any less necessary.
If there is population growth you would expect there to be more jobs like that. But you wouldn't expect the percentages to shift much unless you are under the delusion that the people working those jobs can easily transition to a high tech job if one becomes available. Newsflash: they can't, as a general rule. (The exception are high school and college students who are developing technical skills and working other jobs while they do; but even that won't change the percentage of people in low-skill jobs, because someone else will just take the low-skill job they left).
Unpleasant but factual: life is a pyramid. Each level at the top takes a much wider level below it as support. To have your tech executive, you need executive secretaries and managers. To have your managers you need tech workers. To have your tech workers you need computers and offices; to have computers you need IT staff and to have offices you need janitors, construction workers, electricians, air conditioning guys. To have all of them you need cooks. To have cooks you need food, which means you need farms, and the farms need farmers. And so on, and so on.
And no, labor saving technologies don't necessarily help. They eliminate some of the jobs from lower levels of the pyramids. They don't make the people there any better able to fill jobs at higher levels. Some of them already have the ability to fill those jobs, perhaps with training to help. Some don't.
