> This is obviously an issue that the far right continually talk about.

That’s labeling. Neoliberals coined the term “far right” to refer to a group that to the left of the conventional right on economic issues.

> increasing the salience of an issue on which it has long been perceived as having a comparative advantage

The Danish left predicted (imo, correctly) that the issue would remain and get more salient due to external factors. Then they got on the right side of it.

The alternative approach is to hope the issue will reduce in salience. The problem is that the unruly coalitions that you need to stop far right parties can’t meaningfully give their constituents anything else they want. This is the problem in Germany, France, and the UK.
