My "old guy advice having been thru several recessions since 1974" and having lived in a car for a whole Summer in 1979. Everything is upside down now and there really isn't a lot of advice for what is coming as we (US) have never actually been here before.
My advice is The Basics - use the hell out of that credit card *but* pay it off every month like clockwork. Statistically something like 53% of credit cards in the US have a monthly balance and of that 53% something like 90% are borrowed to the hilt. That's a big chunk of money in interest. Few things are more expensive than credit card debt.
Save money every week - no matter how little - even $10 a week if that's all you have. Get it invested/diversified. Don't leave any more cash in the bank than you need for a couple months of bills. Money in yer checking and bank saving account is like throwing money away. Even CD's don't pay jack shit now.
Learn to Live Simple and not beat yourself up because you are driving an old car or wearing simple clothes - do not scrimp on important shit like healthcare, eye glasses, shoes and tools. EAT AT HOME and learn to cook great tasting, healthy, and satisfying meals instead of eating crap at MacDonald's, Taco Bell, or even your local restaurants. My Wife and I have not eaten at a restaurant in over 3 years - carry out a couple times as guests at a friends home. I can feed us for days on what it costs us to eat fast food for one meal. Make yer pizzas at home.
It's an employees market now - there are jobs, good ones, literally everywhere. Don't get stuck in the 20th century mindset that conditioned US to grind yer face flat working for assholes. Change jobs - change careers, and always (*Always!*) be looking for more money and more flexibility. I had three jobs in 2017 and every time I moved I made more money. Hold yer employer accountable or leave his ass for a better opportunity. Before you work your fingers to the bone making him rich.
And don't panic or get mean and bitter because we are just starting this road of The Decline of America and The Failed Republic and all the crashing and anger that is gonna grow exponentially over the next couple decades. Chin up and take care of yer health (Mental, Physical, Spiritual) because tomorrow will be another day and you can't get that shit back when it's gone. Put yer money where Rich People have their money because they will continue to get fatter and more powerful as the majority slide into poverty and despair. Rich people know how to save/invest so watch what they do with their money and follow.
