That distribution will yield a very high gini coefficient of very close to 1.

No, it yields a Gini coefficient very close to zero.
The Gini coefficient is defined as 1/2 the mean absolute difference considering all pairs of households:
https://en.wikipedia.org/wiki/Gini_coefficient
A group of people where everyone has the same income as a Gini coefficient of exactly zero. Adding a single outlier will increase it a little. A group of 1001 with 1000 people earning $1 and one person earning $100 has a Gini coefficient of 0.09.

It yields (n-1)|5-p|/(2n(5(n-1)+p)) which is about p/(5n+p).
So it depends on whether the president (p) has $10 or $n^2.
If nobody has any money at all, would you not say inequality is low? If everyone in Tajikistan has $5 except the president, Emomali Rahmon, is inequality not low?
I suspect you are looking for a pairing of HDI and Gini, which factors in both the development (and hence the standard of living) and the inequality.
Sweden: (Gini: 0.25, HDI: 0.933), France: (Gini: 0.31, HDI: 0.901), Canada: (Gini: 0.33, HDI: 0.926), USA: (Gini: 0.48, HDI: 0.924), South Africa: (Gini: 0.65, HDI: 0.709).
Now, Tajikistan has an HDI of 0.66 ("medium"), and Azerbaijan 0.756 ("high").
Kazakhstan might surprise you, the HDI is 0.817 ("very high"). The standard of living there is actually good, in spite of what you may have seen on Borat - incidentally filmed in Romania. Almaty's been on my list of places to visit for a long time :) [1]
