In many western countries this divide is increasing and it doesn't look like it's stopping anytime soon unless measures are taken.
As an example, in the UK, where I live, the median yearly salary is roughly £31k, which means you take home about £2k each month. Start subtracting rent/mortgage, car/public transportation, bills, groceries, toiletries, and just stuff necessary for living and you won't be left with much for pleasure and entertainment, i.e., for living beyond surviving.
Which is btw why I find some HN users are sometimes in such a bubble when they make comments about how they despise ad-supported websites and would love for them to be paid instead; that's lacking empathy, not realising that soooo many people wouldn't be able to afford a system like that, or if they did they would have to give up a bunch of other things instead.
