Needs to worki n all permutations of the text:

poco solidarios : not particularly or not very socially inclusive (vs. co-ordinated)

para tener mayor solidaridad : to betoken (a) greater (level of) social inclusiveness vs. fairness.

I doubt retaining the notion of shoulder-to-shoulder solidarity (apart from the Polish Trade Union) will mean anything to an English-speaking reader, especially in a Latin American context with such well-chronicled disparities of wealth.

Compare and contrast a Co-ordinated Pension with a technical meaning: co-ordination or 'Integration' is a term used in public sector pension schemes to indicate that the potential benefits payable under the Social Welfare system are *taken into account in the occupational pension scheme*.
