I was under the impression that even in other countries, activism is generally separate from the political parties and it's more like activist groups putting pressure on candidates and organizing for them if they are more favorable, and sometimes getting something in return.
I've seen exceptions, but I gather they are rare (and we can already see some change as the party is under pressure to become more "normal" and "competitive").
Which is "ok" as wages will start to go up over time (for some). But some wages don't climb as fast and some people are on fixed revenue (old people, disabled people).
So it requires readjustments
