Hello and welcome to Business Daily from the BBC. I'm Manuela Saragossa. Coming up, immigration and the economy of the USA. Who gets to chase the American dream? It's been a dream for white immigrants. It's a dream that was created for white immigrants and that people of

color have always been excluded from. That's one view coming up here on Business Daily from the BBC.

This last Sunday, a new large group of migrants set off on foot from Central America bound for the United

States. They follow in the footsteps of a larger group of about 3 to 7,000 mostly Hondurans,

who left their country in mid-October and are now in southern Mexico. Their aim, well, work and

opportunities in the United States.

God willing, we will reach the U.S. and help fix the poverty we have in Honduras.

We want to help our families.

We are looking for luck in another country because in ours, we have none.

It's difficult traveling with children because I have to find a way to prepare the baby's food and to carry him in our bags while also making sure my toddler doesn't get lost.

It's been very complicated, but it is to give them a better life.

We're not ready to return to Honduras yet because our lives there are very insecure.

We don't have jobs.

We can't live in our country anymore because there are no jobs.

We come in search of the American dream.

But is the American dream still alive? Or was it always just a myth? More on that in just a moment.

It's not just happening in the Americas, of course. Europe too has had its caravans, migrants from Asia,

Africa and the Middle East, risking their lives to cross the Mediterranean. Many of those

who do manage to make it to European shores

end up working in agriculture. In Almeria in southern Spain, there's a huge industry of

greenhouses growing fruit and vegetables which are then sold in supermarkets across Europe.

The BBC's Simon Reeve went there for a recent documentary which aired on BBC television.
