And sometimes those words are a cover
Indentured servitude was not always benign way of paying off a debt. "Servants" could be beaten, sold, raped with no legal recourse. It was not uncommon for children to be kidnapped in England and sold to ships captains, who brought them to the colonies and sold them at profit. Often, they were prisoners of war, the British kings sent lots of Irish over during their conquests of Ireland in the 1600's.
Some suggest that indenture was the template for the African Slave trade.
Workers from India and other SE Asia companies are recruited for jobs in the Middle East, have their passports seized and forced to work construction or jobs they didn't sign up for.
Here's an example:
He says the methods used by traffickers to ensnare people are similar to those Rahim experienced. “The most common method currently appears to be a false promise of employment with an attractive wage, usually advertised through social media or messaging apps,” he says.

Ask these people if they are "enslaved."
Yes, words have meaning. And sometime those words are used as a cover. This is a form of slavery. A subset, if you will.
And I do believe what is going on in Gaza is a form of genocide. Telling people to leave their homes for a refugee camp, then bombing that camp? Choking off all supplies and aid? Bombing whole neighborhoods to rubble? When this "war" is over, how will they ever rebuild? Their lives are ruined. Yeah, Hamas is evil, but Israel is slowly chipping away at Palestine, stealing their land for decades, controlling the population like animals.
Just because these things don't fit a rigorous definition of slavery or genocide doesn't make it less wrong.
