Maybe this is totally off, and maybe the OP is a troll..
I think some of the biggest upcoming recessions are our poor personal decisions. There are new millionaires made in almost every recession, so learning healthy financial habits, staying out of "liability" debt (cars, credit cards, etc.. or staying out of debt altogether if you can) is one of the best ways to hedge agains the inevitable recession that is going to happen in 1 year. Or 100 years. When you keep options open, you can continue to grow and make money when things take a downward spiral. It's like health and wellness- learning to eat healthy and stay flexible will serve you better than most other approaches - it isn't some mystery big moment, it's building good habits that help you stay comfortable if a big downturn happens
The biggest money to be made usually isn't by holding cash out of the market and waiting for a crash, it's usually in identifying the unique business opportunities inherent in crashes. That's typically where major money is made by individuals in crashes.
I have friends who went into business and equipment buying frenzy with covid.
That's not as feasible to pull off for your average corporate employee who doesn't know business and only has a few hundred thousand tied up in workplace retirement plans, but it is how a lot of people get very rich as a result of a crash.
When times are tough, people sell all sorts of shit at a steep discount, not just stocks.
I bought part of a large business at a 35% discount by buying in at the very worst of covid, because I could afford to have no incone for 6-12 months. The deal totally fell apart, but that was because I chose a bad set of partners who weren't as financially resilient as I was, not because of the financials. But had it worked out, I would have ended up very rich.
I would NEVER have had that opportunity in good times. The business would have sold well over value, and there would have been ferocious competition for it.
That's just one of many opportunities I've come across. If I were interested in being an independent business owner, I would have been drowning in opportunity because so few other buyers could weather the storm of no income as long as I could.
