Yes. Why? Because they are most likely to spend it. If you don't have enough to live comfortably, or to get to work, and someone gives you money, you'll spend it on food or medicine, or a car or gasoline so that you can get to a job. So how (aside from having that person get employment) does it increase jobs?
Basic economics. If people spend more, that means other people are making more money, and need to provide more goods and services. So they hire more people.
You don't want to give it to anyone with a higher marginal propensity to save; you want that money back into the working economy. Basic economics.

The percentage of people working has been in decline since 2008. If you need a clue, subtract 2008 from 1945, and you'll figure it out.
Even with the retirement of the boomers, we have a higher percentage of people working now than in the 50s or 60s.

It won't go on for very long, of course. Eventually, all of the boomers will be retired and then as they start to die off, the percentage will rise again.
Assuming Trump doesn't do more things to damage the economy like his trade wars.
