I agree that Purchasing Power is getting worse each generation, based on this site
Inflation Calculator, 1$ dollar in 1900 is now equal to $0.03. It's crazy to see how much our dollar getting worse each generation and there are no real solutions for this, in my opinion, what we can do is we should not waste on anything like food, gases, technology, electricity, water, etc. Many young people these days love to waste many things and we should change this habit from our kids so the next generation should value for what they have.
Do you expect people not to eat food , have access of electricity, and water just because things are expensive? This are things that people can't do without. No matter how expensive food is people will always spend their last money to afford food to survive. Managing food, water, electricity will not change anything honestly. Things are very difficult, money is hard to get but their are things we will always need in our everyday life .
