It's just inflation! Or like I call it here in Canada, justinflation. Our money goes less and less further every year. It's been a problem for probably at least a century so not really Trudeau's fault but it's been getting worse over the past few years and he sure as hell ain't helping! Sadly not enough people seem to really care enough to want to fight against it or vote the right people in. It's not 100% politic driven but there are policy changes such as lower taxes, less spending and less money printing that could help at least. It's basically a hidden tax really. Even "normal" 2% inflation is not any different than if they raised the sales tax by 2% every year.
Even if you are good at investing it still means that your investments are not as good as they could be. Say you invested money in 2010 and got a 2x return in 2020, that money won't really go that much further than it would have in 2010.
Now days the best investment you can make is a way to save money. Solar panels, wood stove, or even going as drastic as moving, to a place with less property taxes, or off grid altogether, etc.
