What are Chris's values after serving in the war as opposed to others' who did not serve?

Chris becomes an idealist. He seems like he cares about social change and equality for the less fortunate. He thinks he has seen the worst in human nature and is above others who have not served in war. Chris, however, preaches a double standard. He laments Joe's business success and money yet he has no trouble living off it. Although he criticizes Joe's success, he does not help others or get his own job.
