3 lessons we didn’t learn from Great Recession

hold less capital in reserve.

All of this ushered in the 2008 near-meltdown — which was followed by another attempt to impose safeguards, the DoddFrank Act of 2010.

And now? The Street’s political clout is as great as ever, which explains why DoddFrank is now being watered down, clearing the way for another crisis.

The second lesson we should have learned but didn’t is how widening inequality makes our economy susceptible to financial disaster.

In the decades leading up to 2008, stagnant wages caused many Americans to go deep into debt — and they used the rising values of their homes as collateral. Much the same thing had happened in the years leading up to 1929.

And now? The underlying problem of stagnant wages, with most economic gains going to the top, is still with us. Once again, consumers are deep in debt, inviting another crisis.

The third big lesson we didn’t learn concerned the rigging of U.S. politics.

Americans saw the Street get bailed out while homeowners, suddenly owing more on their homes than the homes were worth, got little or nothing.

Millions lost their jobs, savings, pensions and homes, but the bankers and big investors came out richer than before.

Bankers who committed serious fraud escaped accountability. No executive went to jail. Big banks such as Wells Fargo continued to break laws with impunity.

Widespread outrage at all this fueled the tea party on the right and the brief “Occupy” movement on the left. Both eventually morphed into the two anti-establishment candidacies of 2016 — authoritarian populist Donald Trump and democratic populist Bernie Sanders.

And now? Anti-establishment fury remains the strongest force in politics.

Trump has been using it to conjure up racist and xenophobic conspiracies and to create the most authoritarian regime in modern American history.

Sad to say, 10 years after the near-meltdown of Wall Street, we seem to have learned very little. Only worse: We now have Trump.
