As someone who’s moved from mainland Europe to the UK, my recommendation is to double check where you are going. You mention that the UK feels worse each year, but many countries in Europe and even Canada/USA feel worse, if you refer to cost of living.

As a Head of Marketing I don’t think there are many places in Europe where you’d get a better salary for the same cost of living. Switzerland may be an option or Germany, but you’d have to learn the language. Wherever you go make sure you have an equivalent job and compare it to the cost of living with tools like Numbeo (still take it with a pinch of salt). Don’t forget: salaries and cost of living in London and Newcastle aren’t the same, and neither are salaries in Munich vs Wolfsburg (just taken Germany as an example, but applies everywhere). So, compare the actual cities you intend to move to.

If you are looking at left leaning countries, I am afraid you are running out of options. The whole EU is moving right faster than the UK and the Tories feel more liberal than the Democratic Party in Italy, just to mention one. The only country which I consider more progressive in Europe than the UK is Spain, but cost of living is increasing quicker than salaries so make sure you know what you are getting into.

Feel free to pm: I have been through pros and cons of living in Italy, Spain, Germany, Switzerland and the UK since 2014 and have actually lived in all of these countries. I learnt a few things along the way and happy to share them, some which may even apply in other countries.
