Banking now is WAY easier. Balancing a checkbook? All your transactions and your balance are available 24/7 on your phone. Your paycheck appears in your bank account automatically. You used to have to get a paper check at work and then take it to the bank (open 9-5, maybe a little later on Fridays, and 9-12 or maybe 2pm on Saturday) to deposit it. Paying for stuff at the store today? Tap your phone. You used to have to carry cash, or a checkbook (if the merchant would accept checks) and hope you had figured your balance correctly.
I don't remember a lot of lessons about managing credit but we did study simple and compound interest in math and talked about how that can work for and against you depending on whether you're borrowing or saving.
Home maintenance and vehicle care --- covered the essentials in home economics and driver's education. Most people then and now paid others to do that, or went to the effort to teach themselves what they needed to know.
Cars back then were much less reliable than today. Today's cars will go 100K miles easy with little more than oil changes and maybe a new set of brake pads and tires. Cars then needed regular tune-ups and generally started having more major problems after only a few years.
Health care does seem worse now. You don't have as many family doctors with their own or small group practices, where getting an appointment was pretty easy and they actually knew you. But overall daily life is way more convenient now than it was 30 years ago.
