I am in the exact same camp. My belief in free markets has been completely shattered and my political stance on several subjects has changed dramatically over the last years.
I no longer believe in the free market at all.
Of course this isn't the result of a single isolated event. Our lives are poems that constantly re-write and scrutinize themselves after all, like living ink that breathes new pages anew. But if I had to pinpoint one very specific period with a very measurable effect on my position it was the whole Elon Musk saga (DOGE+"heart salute"). A lunatic billionaire seemingly doing what he wants, rewriting narratives, making up facts, history, and saying things which were so evidently false, and showing up next to a president as if he were himself president, never having been elected, was shocking.
I used to really believe that "money followed what was good for society". There would be outliers and some noise, but overall these would be well correlated. I now look back and wonder how absolutely naive of me that was. Billionaires should not be allowed. They are a disgrace to the system. It's actually vile and disgusting to have them in our society.
I'm not an american and I used to dream of going to the USA, perhaps even living there. I now want to stay as far away from it as possible, and view the supposed american dream as either a past reality or effective propaganda I bought into previously. Maybe that's better for america and it's what they need to grow, who knows.
