People are unhappy with the cost of living, and I'm one of them. The only issue I have is why people aren't putting the blame where it belongs.

A recent report from Groundwork Collaborative, a progressive advocacy group, argues that corporate profits drove 53% of inflation during the second and third quarters of 2023 and 34% since the start of the pandemic.

The Federal Reserve Bank of Kansas City found in a 2023 report that corporate profits contributed 41% of inflation in the first two years of the economic recovery following the recession sparked by the pandemic.

Corporate profits are at record highs, and much of that is from how they are squeezing working class people.

So who owns these corporations and stocks? The super-wealthy of course.

The three richest Americans have the same amount of wealth as the poorest half of the U.S. population. And 82% of the global wealth generated last year went to just 1% of the world's population.

The stock portfolios of the top 1% are now worth $23 trillion, and they own a record 53.9% of individually held shares. Meanwhile, the share of wealth held by the bottom 90% of Americans, has declined slightly since before the pandemic, from 30.5% to 30.2%. The total net worth of the top 1%, defined by the Fed as those with wealth over $11 million.

I think it's pretty obvious that wealth inequality and our hyper-capitalist system is why people are so upset.
In order to play devil's advocate, let's look at the anarcho-capitalist side.

“I don’t think [the numbers] mean much at all. I don’t think the gap between the 1% and the bottom 50% is at all meaningful,” Brook said. The former radio host has authored many books, including “Equal is Unfair: America’s Misguided Fight Against Income Inequality.”

“There are questions we should be asking ourselves,” he said. “Why are people stuck in poverty? Why do we have limited opportunities in the United States for people to grow out of poverty? Why is there stagnation around it?”

Yes, why is that? Oh, wait. I do know. It's because the super-rich have so much power in our society and that they've rigged the game against the working class. Thanks for asking. Even the top 9% is beginning to fall behind the top 1%.

How much have they rigged the economic system? I have that answer as well.

A staggering $50 trillion. That is how much the upward redistribution of income has cost American workers over the past several decades.
According to a groundbreaking new working paper by Carter C. Price and Kathryn Edwards of the RAND Corporation, had the more equitable income distributions of the three decades following World War II (1945 through 1974) merely held steady, the aggregate annual income of Americans earning below the 90th percentile would have been $2.5 trillion higher in the year 2018 alone. That is an amount equal to nearly 12 percent of GDP—enough to more than double median income—enough to pay every single working American in the bottom nine deciles an additional $1,144 a month. Every month. Every single year.

That's what those commies at the RAND corporation have to say.
The question is what has changed in America since 1974? Massive deregulation, the crushing of labor unions, and a federal government that has refused to enforce anti-trust regulations for starters.
On one side you have Republicans that are openly hostile to labor unions while promising yet another round of tax cuts for the wealthy. On the other side you have Democrats who refuse to stand up to the wealthy donors while telling them that nothing will change, give unions simple lip service.
While Biden has backed Israel's genocide, Trump accuses Biden of betrayal for not embracing the genocide more. While Dems hate Russia, the Repubs hate China.
So what can be done? Oxfam gave a simple solution.

A tax of up to 5 percent on the world’s multi-millionaires and billionaires could raise US$1.7 trillion a year, enough to lift 2 billion people out of poverty.

The horror! The thought of taxing the wealthy 5% can never be considered, especially when you compare that to alleviating the suffering of a just mere two billion people.
I totally understand why people are upset. I'm upset for most of the same reasons. The problem is that the fundamental reasons people are upset won't change with replacing one party with another, or even by replacing it with a new party. The whole economic system needs to change. But the political system needs to go first.
