Giving this book 4 stars for content and ability to provoke thought, not necessarily for stellar writing. IMHO the characterization and pacing were a bit ragged at times, but as a whole the package was seriously impressive.
Plot in a nutshell: 300 years in the future humanity has the tech to bring you back from the dead as long as most of your brain is intact. Combined with anti-aging treatments, lifespans are now measured in centuries rather than decades. On top of this, the whole planet is at peace and real poverty has actually been eliminated by the most stable political system humanity has ever known: Incorporation. At birth every child is incorporated with 100,000 shares of stock, 20% of which is held by the parents, 5% by the practically emasculated government, and the rest of which is sold to anyone who wants it - in exchange for education, room and board, medical treatment, or just spending money. People then spend most if not all of their adult years attempting to gain a majority in themselves, which will give them autonomy (mostly) over where they work and for whom. While the law prevents one's personal share of stock from dropping below 25%, most never achieve self-majority. Into the midst of this, the "corpsicle" of a billionaire from the early 21st century is unexpectedly unearthed and re-animated. (For a variety of reasons he's the Only survivor from our century: Disney didn't make it!)
This time traveler refuses to incorporate, which he views as nothing more or less than slavery. Neither his new friends nor most of the rest of society can begin to comprehend this, and yet his continuing refusal combined with his personal magnetism and leadership skills ends up causing tremendous upheaval in the whole system as everyone is forced to consider what "freedom" really is.

Like I said, it's seriously thought provoking as you watch just what the protagonist is willing to give up to maintain this precious freedom of his - love, fortune, security... I found myself almost rooting for him To incorporate as the climax drew near. If Incorporation was slavery, it was an incredibly gentle slavery, and the security and peace it provided was Real. I found myself asking questions of myself similar to the ones I did when reading Under the Yoke by S.M. Stirling, another novel about a far less benign slavery and specifically the enslavement of Europeans who did not grow up under the system. In both cases I decided that I would almost certainly exchange my basic "freedom" for the personal and corporate security and even prosperity offered by the alternate system. How Un-American of me! What happened to "Give Me Liberty or Give Me Death?" Hasn't that been drummed into us since grade school?
And yet... how well is our current "Free" society (current trending towards real socialism not withstanding) really working for us? Is it eliminating poverty, abuse, and discord - here at home let alone abroad? These are questions the Unincorporated Man was asked many times by both friends and enemies, and while he freely confessed the failings of the system he remained fanatically devoted, to (at least arguably) both his and the society's detriment.
What, of course, the book Entirely overlooked is that true freedom does not depend on your political system; freedom can come only from God - specifically Christ. Without freedom from sin, everyone is a slave. With that freedom, it doesn't make a hill of beans of difference what political system you're living under. Obviously there are more and less benign societies, and I am frankly pretty happy, not to mention thankful, for the one I currently live under. But I don't think it makes me inherently weak, let alone evil, to admit that I would accept a "less free" political system if necessary - it would not change my actual freedom or lack thereof. The system proposed by "Unincorporated"
Worked, at least as far as the scope of the novel was concerned, and I would have found no reason to try to undermine it...
(But no, I am not voting for the Democrats or their Socialist policies, since I don't think that increases Any definition of freedom!)
