It's pretty universal in the developed world to have some type of long term savings tax-scheme.
In us it's 401k/roth. In canada it's tfsa. in uk it's isa.
isa/401k/roth has pretty low caps. tfsa and isk has no cap.
But yea, considering I pay close to 50% tax it's remarkable at the same time I can speculate in the market, make 500% and pay 1% tax on it. Or that people with actual money pay so little.
