Yes, these things are fought for - by liberal, so-called woke politicians. National Insurance (NI) started in 1921 in the UK via the efforts of David Lloyd George, the Liberal Chancellor of the Exchequer, not by struggle. Lloyd George studied Germany, which had compulsory NI since 1884. Longer than a few decades.
There are 78 countries with universal healthcare (Countries with Universal Healthcare 2024), and none have ever demanded an end to it. Again, this is due to stupid politicians. This includes Thailand (Thaksin's 30 Baht scheme is counted as universal healthcare).
Poverty, as you alluded to, is the result of modern governments simply not caring, e.g. the USA, or not being able to afford it, like some countries in Africa.
