When I was young (and poor) I also believed that being rich meant having Scrooge McDuck piles of cash to swim in.
After my first big RSU payout I quickly realized that nobody with more than a few 100k in assets keeps anything close to the majority of them in cash. Savings accounts are for the poor. Anyone, even in the every day millionaire level, keeps most of their wealth in non-cash investments, leaving only enough cash to cover crisis situations. Especially with inflation this high, holding cash is literally throwing money away.
Nobody has a bank account with 8 zeros, except maybe lottery winners that never learned the basics of asset management.
