That definition is way too broad and open-ended.
Anyone can use it, anywhere, anytime.
Gypsies are not being denied access to education, or jobs for that matter.
This is simply false.
I know, I live over here, remember ?
They are plenty of programs and schools that accomodate, and when
possible, integrate Roma students.
The problems start when the parents refuse to send the child to school,
or the kid shows up tired, hungry and beaten.
Not in the best shape to learn something.
And of course following on later,
they cannot accept any job that requires even a basic education.
So they sit on social assistance, pick up what money they can, and continue
the cycle for the next generation.
And your last point I agree with

front line judgements should be possible from selected countries.
Hopefully that change can be made soon, cause the visa bit
will not be positive.
