The 'Left' has gone so far that the 'Right' seems reasonable these days in comparison to many people.
Historically, this is nonsense. The world isn't the USA, and this trend started way before anything you're thinking about.
USA started moving towards the extreme right with the Tea Party in 2010, and accelerated in 2016. That's despite Obama having pretty much the most conservative start to his presidency possible (went explicitly pro-corporate to bail out the banks with zero repercussions for them, used entirely conservative ideas for Obamacare, came out against gay marriage, did nothing whatsoever on race issues, etc.). Obama was more conservative than pretty much every president between 1932 and 1980, Democrat OR Republican. So how can you claim "going too far" is what triggered people to go right?
That sociopath Duterte became president in 2016. What "too far left" thing was going on in the Philippines?
Fascist Modi became Prime Minister in 2014. How had India gone "too far" left? You're talking a place where it isn't even legal to be gay.
Conservatives won power in UK in 2015, and did Brexit in 2016.
Netanyahu took power in 2009.
Bolsonaro became president in 2018 despite the previous leftist president being super popular.
Bukele became president in 2019.
Claiming that right-wingers win because the left has gone "too far" is a complete myth. The reasons the right are surging are pretty obvious, and they've happened before.
1. The "Great Recession" brought a loss of jobs and popular discontent, especially among the working and lower middle class. Right-wing populism has always surged in periods of economic distress (see the waves of fascism that swept across Europe during the Great Depression).
2. When racists get discontent, they blame minorities. Right wingers stoked the economic discontent to blame immigrants for completing with jobs. "Don't blame the corporation that won't pay you, that laid you off, that took its factory abroad. Blame...THAT GUY OVER THERE!"
3. The post-911 mentality of fearing Arabs and Africans allowed identity nationalists to double down on the economic discontent and claim security issues as well as islamophobia skyrocketed.
4. Social media severely increased the pace at which hate-based messages spread, and Ethnic Nationalists found that simple hate messages, even when they're outright false, traveled far more efficiently and became viral more easily than nuanced pushback does.
5. When Covid hit, populist fascists tried as much as possible to blame all hardships on government, even in places where conservative governments were in power. Lost your job? Blame immigrants and liberals. Supply chain issues? Blame immigrants and liberals. War in Ukraine is killing gas and food prices? Blame immigrants and liberals. Corporations and price-fixing? Blame immigrants and liberals.
I hate the trend, but the causes seem damn obvious. Great Recession was 2007-2009, social media started taking off almost the exact same time. And 2010 was when right-wingers started winning elections.
