I disagree with the whole renting = anti wealth idea.
I also disagree, at least to some degree that savings is the foundation of wealth building.
Maybe if you're interested getting wealthy at 60 in a wheelchair (exaggerating here a bit) it's a great road to go down on.
Buying a home doesn't make much sense to me as far as being the prototypical wealth building mechanism -the home is a resellable asset that typically goes up in value, but t's far more inefficient than other assets -namely, business assets -if you're looking to build wealth.
If you want to build wealth before you're too old to enjoy it, you're far better off renting and putting your cash to use in the acquisition of business assets -whether it be IP's, products, actual business', etc. Assets that can grow far faster than the inflation rate or any Oceanside home can and actually provide cash flow for the acquisition of other assets in the meantime.
I have nothing against "saving" or home purchases -but I don't consider them to be anywhere near the best wealth building mechanisms.
They work as far as wealth building across generations -which traditionally is why the home was the greatest asset of the middle class. But if you're looking to break out of middle class territory, it becomes pretty irrelevant whether you're renting or owning in the larger schemes of things.
