I don't know if I want to harp on them too much, die Linke is pretty much only a thing in eastern germany. The west germany has basically suppressed them heavily, first by what some historians would call a 'colonization' of east germany due to just how fucking bad reunification was for eastern germany, as well as deliberate neglect by western germany letting the situation spiral out of control. A lot of Die Linke politicians were also illegally surveilled and harassed and were often smeared as red fash using horseshoe theory stuff.
This leads us to now where they just suck like they are to the left similar to how AOC is to the left of Biden unable/unwilling to do anything so they'll keep losing ground to the AfD they'll not get anywhere.
Honestly no the older I get the more I am against 'rewarding hard work' because in praxis it always comes down to people getting pressured to do things that will inevitably fuck over their body or cause other complications down the line. Construction workers that 'work hard' by carrying two sacks of cement instead of just the one then later complaining about back problems or slipping and seriously injuring themselves. People working shifts without proper periods between them wrecking their sleep hygenie and getting astronomically higher stroke risk as a result the list goes on. Workplace injuries and complications are almost always down to either social pressure to 'work hard and hustle' or a shitty boss that just ignores labour laws.
It's not on workers to work harder it's on management to hire more people.
