Not only Obamacare.
Those with no real marketable abilities, those too lazy to work, those with no "living" skills (no idea how to provide for their own needs), those who rely on the Feral Government for Housing, transportation, food, healthcare and their other needs are the chattel of the government and by extension the democrat party.
And there are already many, many millions who fall into that category.
They are warehoused on the government/democrat party plantations, fed and watered like sheep, until it is time to shear them for their votes on election day.
That is how Obama got elected and why it will be an uphill struggle for any republican to get elected president until the country returns to sanity.
The odds are that it will collapse before politicians are forced to abandon their "Moocher State" mentality.
I agree that those that have traded their freedom for a meager existence have also been enslaved, however that is a voluntary enslavement. They were still free, if they wanted, to walk away from their self imposed slavery.
That is much different than the federal government demanding that you eat arugula (or what not,) that you exercise, that you are not allowed to take part in some activity (gun ownership,) or that you are not allowed to consume some product.....
Plus, they mandate that you purchase your own enslavement from another private entity.
Then, after a lifetime of taking our masters abuse, we will still get denied medical treatment when we have lived beyond our usefulness.....
We have been enslaved, with no options left......well....
