> None of this would be possible in a civilized country.
I think the same concept exists in many civilized countries. In Germany it's called Erzwingungshaft (https://de.wikipedia.org/wiki/Erzwingungshaft) and can be up to half a year for refusing to testify (though you can refuse to testify against yourself or close relatives without repercussions, similar to the 5th amendment).
In Germany Ordnungshaft (https://de.wikipedia.org/wiki/Ordnungsmittel) is the measure for refusing to testify. It is strongly regulated and can't extend longer than 6 weeks without going to a higher court.
Erzwingungshaft is incarceration for failure to pay fines or penalties.
