Remember we're probably not talking about a single person, but an company. His company is likely over valued because of how famous his books/seminars are. And yes, while he probably has real estate, it's probably not the same business. When they come after him, they probably hit one side of the business and not the other.
It's very possible someone gave him a ton of loans that are undeserved because they overvalued the names. We see it all the time in the stock market.
Not sure of your means, but we can boycott. Organizations like Trader Joe's and Aldi are a bit cheaper than their competitors while offering also using different sources. Likewise organizations like H Mart or your local farmers market source locally, giving the middle finger to Tyson (who claims inflation and profits) and Kellogs (who uses shrinkflation to claim profits). Obviously this doesn't work for everyone, but I think the majority of city dwellers can make these moves. This also is a fuck you to any local grocery stores trying to do the same bullshit (Walmart).
In the same vein, and what I've done, alternative meal companies have come A LONG way. The company Huel has a instant noodles, pasta, and candy bars that are macro balanced with vitamins and nutrients all for about $5/meal. I know most people will skip this, but they're actually really good. Mac N Cheese, pasta Bolognese and Cajun pasta have actually gotten me to go mostly vegan. There's another one called Outstanding Foods that has cheese puffs, cookies and pork rinds that are macro balanced and delicious as well. My daily meals are often some pasta like Mac N Cheese, one of the Huel shakes (I have a ninja creami so this is ice cream in the summer), and coffee mocha cookies, and another shake. That's 1800 calories with balanced macros and vegan that I didn't have the really cook or think about. If I'm working out, I swap the last shake for a protein shake.
