This article is actually about retirement investment accounts. Your point is still taken, you can't eat investments and the gross profiteering has not subsided.
“Almost one-third — 31%— of respondents reduced contributions to their 401(k) plans. Meanwhile, 26% said they’ve cut back on paying down debts, 25% reduced their long-term savings, 24% scaled back emergency and short-term savings, 19% whittled down contributions to health savings accounts and 13% reduced contributions to a college savings fund.”
More than retirement/401ks only.
And even if it was only retirement accounts that's the investing most people do. If you make it to the point where you've maxed out all your tax advantaged accounts then you're doing way better than average.
