Everyone should review the comments made to the original article over on the sfgate site. There is lots of commentary about why should WWII-era Jews get their stuff back while miscellaneous historical injustices were not reversed.
“40 acres and a mule”
“Native American historical lands”
etc.
Which is actually a reasonable question. There were a great many historical injustices and confiscations of property during the 20th century. If one is going to pick out one or more as being more worthy of restitution than others, one should at least be willing to explain why the distinction is justified.
