All of those add up to under $50/month. When I was a kid, everyone around (in small town midwest) had a cable package for over $100/mo and many were by no definition rich.

Once you factor in internet, the current cost is not too different.

Sure, but internet is a basic necessity at this point regardless of if you choose to stream content.

when you subscribe to cable tv, you pay for content and delivery, so i think it is far to compare the price of streaming service including the price of internet

While I get that that's more money than a lot of people have to spend, all of those combined are cheaper than a typical non-basic cable or satellite plan even today - after they know they need to compete with streaming services. It's a lot cheaper (especially adjusted for inflation) than those services were 10 years ago. So anyone that could afford content then is probably able to afford it now, but they have better options - so they might choose not to.

I've checked out Netflix in Russia, all the current and 1-2 y.o. shows are available with some random films. Also, the only language available to choose (except English and original if it differs) is finnish!
