I think you should be fine. Those points are most definitely valid, provided that you expanded on your argument with things like:
- Recession lowers aggregate demand which saw cutbacks in production and closure of many firms
- Unemployment was worsened by structural change and microeconomic reform. Loss of jobs meant that the people found it difficult to re-enter the workforce because job vacancies required higher or different skills
- Reluctance of business firms to employ workers again since the general consensus is that: the longer you're out of the industry, the more likely you'll lose your skill set in your respected field
Other than that, you should be good.
EDIT: the latter two I touched upon are related so I guess that may augment your analysis alongside with statistics. And if you mentioned the short and long term implications then it shows you know your stuff.
