Earlier quoted context omitted.
Interest rates for banking accounts for quite some time have been low. 3% is very high for the USA so it' s a pleasant surprise for many people.
Also 3% is astronomical for Euro zone. Here you typically have 0.01-0.1% on saving accounts (only for 100k Euro and below), and negative rate on checking accounts (most people usually pay 7-12 Euro per month for checking accounts and 20-40 Euro per year for Visa card).
I haven't checked everywhere in the eurozone but a lot of major banks have online brands/products that are typically free. You should be able to have at least a checking account and a debit card without paying any fees. "Neobanks" are also a lot more developed than in the US: see N26, Revolut, Ferratum, ...
Savings accounts yield nothing, but that has nothing to do with retail banks :) That said, you can find fixed-term deposits between 1 and 2%: https://www.raisin.com/
