It’s the Fourth of July, and as you head to a holiday beach or barbecue, look around your town. Take a moment to notice—and appreciate—all the many small businesses—and large ones too—started by immigrants. As we celebrate America, we also celebrate what America has meant—and continues to mean—for immigrants from throughout the world.

A few years ago, I toured the neighborhood in Flatbush, Brooklyn, where my father grew up. My dad, Alex, was the son of hard-working, ambitious immigrants from Eastern Europe. Like most immigrants, they came to this shore seeking a better life for their children—more economic opportunity, more political and religious freedom.

Walking around my father’s old neighborhood was like taking a trip back in time—except these immigrants were from the Caribbean instead of Eastern Europe, black instead of white, and spoke with a different accent. But they were living much the same lives—students pouring over homework in the library, kids playing in front yards, parents going off to low-paying service jobs or starting their own small businesses.  Clearly, America meant the same to them as it meant to my family. And I could clearly see that these children were our future doctors and lawyers—and the future of America.

Immigrants are America’s not-so-secret strength. Some immigrants come here to save their lives, like the children refugees from Honduras. In many countries, being gay is punishable by death. And in so many places, girls and women are not allowed to be educated or pursue careers.  Most immigrants experience hardships—sometime death-defying hardships—to come here.

Throughout America’s history, most immigrants have been economic immigrants. They may come here for greater freedom or safety, but opportunity is generally the greatest motivation. (From Canada they come for the weather).

By being a welcoming place for immigrants, we make a bargain—they revitalize our country, and we give them a home—ideally, a welcoming home.

Immigrants overwhelmingly stick to their end of the deal.  They bring us fresh, new ideas. They become our scholars. They win Olympic medals. They bring new food. They create businesses—small businesses—even entire new industries. They keep America vital and competitive.

Here are just a few statistics on immigrants’ effect on business and job creation: 
Think of some of the many immigrant entrepreneurs who have made America what it is today: 
  • Levi Strauss: The man who invented blue jeans emigrated from Bavaria in 1850. There are few things more American than a pair of Levi’s!
  • Liz Claiborne: This Belgian-born fashion designer co-founded the famous label bearing her name. In 1986 Liz Claiborne Inc. became the first company founded by a woman to make the Fortune 500.
  • John W. Nordstrom: The man behind the famous, upscale department store chain came from Sweden in 1896.
  • Eugene Kleiner: Austrian born Kleiner was one of the ‘traitorous eight’—the founders of Silicon Valley—and the original founder of the famed venture capital firm, Kleiner Perkins Caufield & Byers.
  • Elon Musk: Tesla Motors, Space-X, PayPal, household battery power. This serial entrepreneur emigrated from South Africa to Canada and later here to the US.
  • Sergey Brin: The co-founder of Google was born in Moscow in 1973 and came to America at the age of six. Where would you be without Google?
  • Sofía Vergara: Perhaps known best for her role as Gloria Delgado-Pritchett on the hit TV show Modern Family, Colombian-born Vergara also started the Hispanic talent agency Latin We and launched a clothesline for K-Mart. Woo hoo!

We are all—with the exception of native Americans—the descendants of immigrants. That’s something to celebrate this Fourth of July.
