In my 2 cents,
the people who take the longest vacations when unemployment rates are low have no fear of losing their jobs
--too specific;this talk about those who take the longest vacations
travel costs are lower during times of low unemployment
--this is actually a weakening statement;if it is true,we can't reach the given conclusion
most people prefer to work full-time jobs
--totally out of scope
workers’ perceptions of their own job security are in some way related to the unemployment
