First, all my congratulations for taking the time to set up this discussion and backing it with facts.

As a summary:

• There is significative evidence that liberalization rises significantly the revenues of the richest, and only them. (see figures for UK & US) Which tends to prove that the dominant ideology about liberalizing is rather a plea "pro domo" than a objective analysis

• On the contrary the poorest do not benefit from this liberalization, particularly where health is concerned.

• This clearly advocate for a real debate for the kind of society people want to live in, and if democracy is rational, it should not be too much "liberalized"

However, this article is not totally conclusive regarding what needs to be done.

People in France do work less on a whole:

• first because the rate of employed is too low ( went for France from 59,5% in 1995 to 63,1% in 2005 ) (against resp. 68,5% to 71,7% in UK) (sce: eurostat)
  
• second because they work less hours in the year (UK: from 1734 hours in 1995 to 1669 hours in 2004, F: from 1626 to 1520 hours)
  

 (sce: http://oberon.sourceoecd.org/pdf/fact2006pdf/05-01-05.pdf)
(theese data take into account part-time workers)

So it is quite obvious that France is getting poorer as a whole because we work less in France. But the first reason is unemployment, long unproductive studies and early retirement. Not "35H"
This could however be a choice of life. In reality, median wages are low and most people prefer to work more

However, we still don't see here how to create those jobs  
From that matter, this article does not help us to know if liberalization is good or not. We're only told that public spending can be a solution, if you can afford it

My opinion on this is that we need to boost the ability of our Small Businesses to export, and benefit from worldwide growth
