Outside political circles, there seems to be a clear consensus that we could have done more earlier. Covering that up with "but China" is a political stance, despite some truth.

I don't know what this means.. What's a "quick person". Somebody who's negative today can be positive tomorrow. You can't test everybody every day or even every week or every month using today's PCR swab test.
In the White House they supposedly use the Abbott system, which has accuracy issues, to test everybody coming near the President regularly (not sure how often exactly) but that system gives results in minutes. Quite likely more and more businesses are going to be doing something like this.

Race Is On to Create Rapid Covid-19 Tests for the Fall

Even as coronavirus testing ramps up around the country, businesses and public-health authorities seeking to safely reopen are hitting a speed-bump: Standard testing techniques still require sophisticated lab equipment and can take hours or even days for results.
To stretch beyond the lab, test developers are racing to produce next-stage technologies that could allow for rapid widespread testing as quickly as an at-home pregnancy test.
“The truly ideal test is the test that you can do in your house every morning,” said Elizabeth McNally, the director at the Center for Genetic Medicine at Northwestern University.
Yet diagnostics experts estimate wide access to quality rapid tests is still months away. Among the challenges is finding noninvasive ways to collect the patient sample while maintaining the sensitivity of current standard tests. The nasalpharyngeal swabs used in most current Covid-19 tests are invasive and difficult to successfully conduct in a home setting.
The industry is trying to move quickly, especially before flu season arrives in the fall. That is when public-health experts worry about another surge of Covid-19 cases, and the ability to quickly distinguish between respiratory illnesses would become even more crucial.
Mammoth Biosciences . . . . [a] South San Francisco biotech is working to develop a hand-held rapid test for Covid-19 using the Crispr system. The technology is best known for enabling gene editing and is now being turned toward detecting the genetic signature of the coronavirus.
Sherlock Biosciences in Cambridge, Mass., earlier this month received emergency use authorization from the Food and Drug Administration for a Crispr-based Covid-19 lab test that can provide results in an hour. The test is the first authorized Crispr-based infectious-disease diagnostic, the FDA said, but is still limited to specialized laboratories. The company aims to submit a test that can be used in urgent clinics and doctors’ offices for authorization in the fall, said Sherlock’s chief executive officer, Rahul Dhanda, while the rapid hand-held test is still further off.
Mammoth signed a deal this month with GlaxoSmithKline PLC’s GSK Consumer Healthcare to develop its rapid test. A GSK spokesperson said they aim to have a prototype before the end of 2020, and potentially available in clinics by the first quarter of 2021. Over-the-counter availability to consumers would come after that, the spokesperson said . . . .

This is the sort of thing we are going to be doing within months, and it will largely replace the current system of swabs and doing tests in labs taking days. But it will be centered on works sites and other locations who consider it worth the money and necessary to maintain full scale activity. It is not something that's going to be used on the public at large (that is, "en masse"), at least at first.
I doubt much of the public is even that interested in being tested. I'm not until/unless I feel sick or think I've been exposed.
By the way, as American business becomes convinced that to stay open and maximize business activity they are going to need to keep the infected out of workplaces, I predict that America will blast ahead of the rest of the world in testing. But it'll be done by private industry, not government.
