Dig deeper...why are students suffering?...because France can't afford to pay for teachers and
facilities...and why is that?...The nation's Debt has gotten out of hand and it's affecting all facets of the economy...so Unions and others are joining in to show their frustrations.
Now look at the link for Debt/GDP ratios amongst all nations...see what Trump has been doing lately with his Trillions for Tax Breaks and an Illegal War...etc,...a Total of `$11.6T added during his 1-1/2 terms in office. Not at all 'Fiscally Responsible'...and we're on a path to a similar fate if Congress doesn't rein him in. You'd better hope the Dems take control of the House and Senate in two weeks.
