Real Estate - highly leveraged mortgage with a low, 30-year, fixed interest rate. Keep the payment low enough that you're sure you can afford to hold it. The 30 year mortgage rate is still pretty low, especially compared to current inflation. You win on the equity gain, you win on the inflation, and you win on taxes. (given recent trends, laws, and rates)

In a place where people will want to buy houses for the next 30 years, at an inflation-adjusted price which preserves the value of your investment,
and assumes you've already bought the house or can do so in the near future while mortgage rates remain low, while the struggle is that the cost to get into the market is rising at crazy multiples (30% yoy?)
and assuming enough economic stability that you can be sure to make the payment even if your job moves.
People thought real estate was a can't lose investment back in the run up to 2008 as well. While real estate can be a good investment for many people, a lot of places are well into bubble territory (Canada, Australia, and China come to mind).
