There was a post on !mildlyinfuriating@lemmy.world called "Lemmy is losing the war against reddit. How do we change things?" Looks like it was removed but there were a couple good discussions there. In a discussion with (I think it was) @hendrik@palaver.p3x.de we came up with this.
I would say there is no definitive "Left" or "Right". It depends on which countries policies we are basing this on. If I compare German politics to US politics you would not even consider the Democrats as the left
It shifts with each country.
I think while the political compass doesn't show every aspects it shows that there are more attributes to consider when talking about political direction.
While I for example might consider myself socially progressive and more on the left side on the spectrum I'd also consider myself more conservative when it comes to fiscal policy for example. That's why I also argue there is no single correct political orientation if you want to be a good person.
Politically speaking, there is a clear-cut answer for what a good person is, I think. Someone who wants to improve the life of as many people as possible - even at the risk of decreasing their own circumstances. And that is usually what the left should aspire to be.
Socially speaking, this usually means to grant the same rights to everyone. Giving up privileges, overcoming the bias one might have against certain groups and stopping to exploit them.
Fiscally, this usually means supporting the poor. Conservative fiscal policies are mostly based on greed - 'conserving' the wealth of those who already have it at the cost of the poor. Going to your example, Germany, conservatives are all about taking money from the poor (Bürgergeld, Bafög, etc.) while denying any policies against the rich (just listen to the conservatives speeches during the vote of confidence: 'These so called super-rich people don't exist! We can't take from those! They are all family-owned businesses! Their wealth creates jobs!' [loosely translated summary of both Merz and Lindner] Which is just emotionally charged trickle down nonsense that has been disproven multiple times over.). The myth of 'fiscal responsibility' is also easily disproved if you look at Merz' policies he is campaigning on - they have been proven as nonsense within days if not hours.
It's easy to see which is morally the better choice, both if you're poor and if you're rich. Robin Hood isn't recognized as a heroic figure for nothing.
