IF STAGNANT WAGES, near-record inequality, climate change, nuclear buildups, assault weapons, mass killings, trade wars, opioid deaths, Russian intrusions into American elections, children locked in cages at our border and Donald Trump in the White House don’t, at least occasionally, cause you feelings of impending doom, you’re not human.

But I want you to remember this. As bad as it looks right now, as despairing as you can sometimes feel, the great strength of this country is our resilience. We bounce back; we will again.

Not convinced?

First, come back in time with me to when I graduated college in 1968. That year, Martin Luther King Jr. and Robert F. Kennedy were assassinated. Our cities were burning.

Tens of thousands of young Americans were being ordered to Vietnam to fight an unwinnable and unjust war that ultimately claimed more than 58,000 American lives and the lives of more than 3 million Vietnamese.

The nation was deeply divided. And then, in November of that year, Richard Nixon was elected president. I recall thinking this nation would never recover, but somehow we bounced back.

In subsequent years, we enacted the Environmental Protection Act. We achieved marriage equality for gays and lesbians. We elected a black man to be president of the United States. We passed the Affordable Care Act.

Even now, it’s not as bleak as it sometimes seems. In 2018, a record number of women; people of color; and lesbian, gay, bisexual, transgender and queer representatives were elected to Congress including the first Muslim women.

Wind and solar sources of energy are rapidly becoming cheaper than fossil fuels; 18 states raised their minimum wages.

Even in traditionally conservative states, surprising things are happening. In Tennessee, a Republican Legislature has enacted free community college and raised taxes for infrastructure. Nevada has expanded voting rights and gun controls. New Mexico has increased spending by 11% and will dramatically boost its minimum wage in the coming years.

Teachers have gone on strike in Virginia, Oklahoma, West Virginia, Kentucky and North Carolina, and won. The public sided with the teachers.

In several states, after decades of “tough on crime” policies, conservative groups have joined with liberals to reform criminal justice systems. Early childhood education and alternative energy promotion also have expanded nationwide, largely on a bipartisan basis.

In 2018, South Carolina passed a law giving pregnant workers and new mothers more protections in the workplace. The law emerged from an unlikely coalition: supporters of abortion rights and religious groups that oppose them. A similar alliance in Kentucky enacted laws requiring that employers provide reasonable accommodations for pregnant workers and new mothers.

The arc of American history reveals an unmistakable pattern. Whenever privilege and power conspire to pull us backward, we eventually rally and move forward.

Sometimes, it takes an economic shock like the bursting of a giant speculative bubble. Sometimes, we just reach a tipping point where the frustrations of average Americans turn into action.

Now, come forward in time with me.

Look at the startling diversity of younger Americans. Most Americans younger than 18 years old are ethnically Hispanic, Asian or Pacific Islander, African American or of more than one race. In 10 years, it’s projected that most Americans younger than 30 will be.

Three decades from now, most of America will be people of color or of more than one race. That diversity will be a huge strength. Hopefully it will mean more tolerance, and less racism and xenophobia.

Young people are determined to make America better. I’ve been teaching for almost 40 years, and I’ve never taught a generation of students as committed to improving the nation and the world as is the generation I’m now teaching. A record percentage of them voted in the 2018 midterm elections; another sign of our future strength.

Meanwhile, most college students today are women; which means that in future years, even more women will be in leadership positions in science, politics, education, nonprofits and corporate suites. That also will be a great boon to America.

To state it another way, there is ample reason for hope.

But hope is not enough. In order for real change to occur, the locus of power in the system will have to change. Millions will need to be organized and energized not just for a particular election, but for an ongoing movement; not just for a particular policy, but to reclaim democracy from the moneyed interests so that an abundance of good policies are possible.

The oligarchs and plutocrats would like nothing better than for the rest of us to give up and drop out. That way, they get it all.

But we never have and we never will. Preserving and expanding democracy has been America’s central project since its founding. It’s an unending fight. And no matter how bleak it may look, we will never stop fighting.
