There's nary a person in this country who hasn't been a victim of the government at some point in time, and certainly their ancestors have faced harsher grievances. So many people immigrated to the u.s. due to disparate treatment abroad, came here dirt poor with their property and belonging abandoned back home. Many arguably began in a worse position than the freed man, some better. None of these people seek reparations. All value the "opportunity" this country affords.
That is why the idea of reparations seems so petty, unjust and unwarranted. The situation is barely unique, save for the specific government causing the harm (which it has subsequently corrected).
There is no end to the damages that the u.s. government would have to pay. Everyone is born into a unique circumstance, and to generally pay one group of people money for the most common circumstance their designated group is born into is to afford a windfall to some, prejudice to others, insufficient compensation to some, and harm to everyone else. It is absolutely preposterous that intelligent people are willing to entertain such a sloppy and unjust exercise.
