Think about what you could buy with 1$ five years ago and now think what you can buy with that 1$. The USA prints the dollar like crazy and inflation hits hard. 1$ is 1$ today but it's 0.9$ tomorrow, 0.8$ the day after tomorrow and etc...
To be fair, one dollar seems like a wrong decision for an example lol, you couldn't buy anything for a dollar five years ago, and not like you can buy much with it today neither.
But yeah, you are right with the idea, what worths something five years ago, worths a lot more now. So what can we do? We could keep on complaining about it, and that's going to end up not helping us at all, life is pretty serious and troublesome and its not looking good for the future neither. Or, we could use this information for our future and make more money, isn't that better?
We know that things go up in price, we also know that USA (or all other nations) print money like crazy, so what can we do to help us? What can we do to make sure that this system could profit us? We could just learn to use this in our advantage, and in return we could make a good profit from it, smarter isn't it? That way we could say that its going to actually be a profitable thing for all of us. That is just a simple idea, make inflation your helper, not your enemy.
