As said: If you swapped $10000 to silver in 1990 you could swap it back to $12683 in 1995 You made +27% in 5 years. Just 1 example. There are in that 14 years examples (peaks / bottoms instead of my averages) that are +80% If you show a very long timeframe (30 years), then things that appear flat, can actually be quite less flat. $120 to $200 is the same profit as $1200 to $2000
Jan 1990 was $5.23 Jan 1995 was $4.68 Your example isn't great. If you bought in Jan 1990 you would have only been able to sell at a profit in Jan in 3 out of the next 13 years. That's pretty bad. If you held on thinking it's going to the moon, you had to wait 21 years to get a 10 bagger. And a 10 bagger has only happened twice in 40 years, assuming you buy and sell at the right time, because both were brief peaks.
What did you do here: you "wrote" your own conclusion by pickpecking a year and even a month, compare it with another pickpecked year and month. My example: If you swapped $10000 to silver in 1990 you could swap it back to $12683 in 1995 You made +27% in 5 years. ...wasn't that pickpecked - it used an annual average, thus gave plenty time to trade, and despite that, it delivered 27% profit. Your turn, boss.
Though, alot things became cheaper in that "actual" way. Due to scientific / technological improvements and automation due to computers, that became affordable for the mass in the nineties. The big question today is how that will be in "our" next decades. Because this is the single big price inflation - compensator in the economy. The central planning thieves club throttles its money creation according to the degree of this improvement, to avoid too fast price inflation resulting in their currencies being dumped for other products, making their monetary frontrun on the market fail and their monetary thievery thus fail too. Apparently, todays central planners foresee alot less compensation in the future, and hence they decided to falsely suggest big money creation > big spending (the QE scams), and frontrun the markets they try to lure speculators to, inflicting them higher prices for those products, and thus wasting their savings.
