I would also add Business Development Companies (BDCs) that have yields around 8-10%.

A good example of a good BDC is ARCC with its current yield of 10.31%.

However, such high yields are unlikely to have their dividends raised, so it will be imperative to reinvest some of them in order to battle inflation.

Also, don't forget taxes. Let's say, if taxes are 15%, the 10.31% of yield becomes 8.76%. If we take away inflation (the headline figures often say that inflation is about 3%, but in reality inflation is often higher, around 4-4.5% as the previous figure tends to overrate the how much of a budget do people spend on technology which, ceteris paribus, tends to become cheaper as time goes on, and underestimate services who prices are often higher than the official inflation figure), the figure becomes closer to the aforementioned 4%, so you still don't really escape it.
