Is the inspiration, or manipulation, behind rounding up homeless people in U.S. cities and putting them in camps, the same as what is reported going on in China, with mass construction of minimal housing units capable of group-housing as many as 250,000 people in one location?

As usual, your intuition is serving you nicely here. This, indeed, is the same program, which reinforces the serious and sinister nature of what is going on. And it speaks to the seriousness of what is taking place, when the United States of America can be carrying out a roundup of undesirables to put them in camps, as a parallel to what is happening in one of the least free countries of the world, under communist rule. But that is what is taking place. This is a testing of the waters to see what they can get away with. It will be initially justified is a humanitarian measure that is of benefit to society, and thus a win-win. But this is a dangerous precedent that can well expand and reach extremes of negative treatment, up to and including genocide. So it is, indeed, something to be concerned about. The question is whether anyone in any position of authority will notice or care. That, too, is a gauge of how far-gone society is, in the face of the relentless mind control being implemented to make people complacent and tolerate extreme circumstances that are, themselves, a slippery slope in a downward trajectory.
