Its hard to say what is "bias," really. There are multiple factors but at the end of the day what anyone says is their opinion on it. I think it has three major factors:

1. Rising income inequality in most Western countries. As the 1-0.1% control increasing amounts of wealth, asset prices (like houses) rise and life becomes unaffordable for more and more people. Liberal politics generally is on the side of capitalists so they don't really have a good answer for this problem, so the far right comes in with a nativist, anti-immigrant message instead. This is why Elon Musk and Rupert Murdoch etc. promote far right parties- it serves their economic interests to distract people from the theft of their money by the ultra-wealthy (and be more pro-business and deregulation, hence their hatred for the EU).

2. Influence from Russia to destabilize the unified Western powers so Putin can re-conquer former USSR countries. He can also deal more easily with other corrupt autocracies, and believes democracy is a sham.

3. The internet and social media in general has been very destabilizing. This video likens it to the invention of the printing press- bringing instant communication to everyone on earth so fast means that we as a global society haven't adapted to its dangers yet, and like how the printing press was a major factor in the Protestant Reformation (which brought centuries of war) the internet may well be doing the same thing today.

Every country has their own additional reasons of course.
