Yeah most low-risk assets will pay out slightly lower than the inflation rate, but they're guaranteed. The only way one can actually beat inflation is to take risks.
But like has been said, the risks can't be just blindly taken with huge amount of capital. Keep most of it (like 90% or so) in low risk, like GIC's, fixed terms, bonds, etc. and then put the rest in high risk that has great potential. Then if you lose it, you won't break yourself. But the gains have great potential for returns that could even beat out the rest of your portfolio.
