Unemployment rate is irrelevant to the original question. And the cream of the crop of the unemployed seeking a military career for that reason is not really the cream the military is interested in.
While a misdeamenor is not an automatic bar to becoming a commissioned officer, it will always make things more difficult for any applicant, and impossible for many applicants.
If an applicant is coming off the street, the application is likely to be rejected without further ado. Unless applying for a critical skill in which there is a shortage of officers.
If an applicant is already active duty or reserve or enrolled in an advanced college ROTC program, the military will review the circumstances of any misdemeanor more carefully, and in these cases strong recommendations from senior officers who know the candidate will often make the difference between an application being accepted or rejected.
