How do the RSS Feeds based websites are treated by Google and other search engines?

I found a website usajobsnew.com which collects jobs in all positions from other reputed jobsites in USA and worldwide. I think they are using RSS Technology (Really Simple Syndication) to collect jobs from other jobsites. By displaying jobs from other job sites will affect the number of visitors of that sites. Such websites are making business using the content of other websites. Is it legal to collect data from other job sites? I think it's very simple idea to develop a job site using RSS Feeds. How these types of websites are treated in search engines like Google, Yahoo, Bing etc. (link removed by mod)

The search engines like to see fresh content so RSS feeds are great. The only problem with taking information from another website is (obviously) the legal implications but also the fact that this is duplicates information which the search engines typically will ignore
