The US dollar has been the strongest currency for the past 100 years, yet it has lost 95% of its purchasing value since 1913. Fiat currency will always lose value over time, but cryptocurrency will always gain value over time; the two are moving in different directions. According to recent studies, 40% of all US dollars in circulation were printed in the last twelve months. Every day, they are printing away our wealth. Opt out and invest in cryptocurrency instead.
I would say that 1913 to today salaries did not change as well as it should. The reality is that people in 50s and 60s worked in silly jobs and still managed to buy a house. Tell me, what are the chances of a 30 year old to buy a house, all debts paid off? I can tell you that it is near zero except a few very rich ones. Sure there are rich people in all generations, Mark Zuckerberg had billions before he was 30, but do we base the whole generation on that?
We have people who are at great jobs who still fail to buy a house, even software developers who are seen as one of the highest paid people end up not being able to buy a decent house, maybe a 1 room apartment but that's it. So, there is something going very wrong with this calculation. House is just one example, from school to medical there are many other sectors that we can take a look at. What got better? Working conditions are definitely far better these days, and tech is better too so you get more help instead of doing manual labor all the time.
