This is loser think. This is how losers stay losers, by focusing or obsessing on the negative and ignoring the positive. If every loss is permanent, then so is every gain. And since gains and losses are opposites that cancel each other out,, wgaf about a loss as long as you're net positive. Only losers fret over losses forever.
So according to your theory, the world today is no wealthier than it was 10,000 years ago. Okey dokey
Your defining wealth as " value" "love" "Ease of life through advances in technology" I'm terming wealth as a unit of account. We are on two different pages but that's ok, have a good day.
To me, despite that we making loss in trade most of the time, it doesn't stop us from trying harder to make profit in our next trade. I will advice traders to be optimistic about the future, especially when comes to forex trading.
