The employment rate is not lower. The unempoyment rate is greatly misleading. If you want to understand how screwed up the data is read here.
One of the better measures of unemployment is what is called U6 which is about 14.5% currently. And that does not tell the whole story as it excludes many people like those who opted to retire early or go on disability. The best measure of employment is the labor force participation rate. The actual number of people who are working. That rate is at it's lowest point since about 1981. The growth in jobs is barely enough to keep up with population growth at the moment.
Young people are at a disadvantage in some ways becuase they lack experience. In some fields they'll be hired first because they'll work for less. But in highly skilled areas they lack the experience. A big part of the unemployment problem is still structural. We have 100's of thousands of job openings that many americans are simply unqualified to fill. Many companies are bringing in people to the States from abroad to fill roles in areas like engineering and software design. We have too many kids graduating school with worthless degrees, and not enough in mathmatics and engineering.
The other issue is that top line revenue growth just isn't there. Companies have deleveraged and trimmed their staffs to increase margins. Right now the emphasis in many industries is focused on dealing with the growing regulatory burden, which is counterproductive to investing capital in more productive ways. Which is also bad for job growth in the long run.
As far as a recession being over, that is an economics terms at the end of the day. Technically, the economy could grow at and anemic pace of 1-1.5% for ten years and we would not be in an official recession. However, it would be a prolonged period in which it would feel like a recession for many people, if not the majority.
Regardless of age, there will be growth in the engergy sector in the next decade plus. There are too many resources being uncovered on private lands all over the country with new technology that allows us to look for it topographically.
