No, you have a job in capitalism. That's a system whose main intent is to maximize the exploitation of resources. Capitalism is an idea, a tool, conceived to help societies become better.
The folks who invented capitalism, did not foresee the idea of humans as a simple resource to be exploited. The idea that humans should be exploited as fully as an iron mine, or a foreign market became known as 'laissez faire' capitalism and reached its pinnacle in something known as 'social darwinism' when the Duponts, Rockefellers, Ford, etc, opposed making factories safe for workers because they wouldn't evolve to be good workers if the consequence of death wasn't culling them to produce offspring that were better at factory life.
Most people considered this to be a horrible idea that was counterproductive to the development of a pleasant, prosperous society. Consequently, labor unions were made legal, the precursor to OSHA was created, weekends came into existence as holidays, etc. Which is to say that the open ended exploitation of workers was no longer considered to be legitimate.
Since then, it was assumed that families needed time when everyone had the day off. Otherwise, the odds that twenty or thirty family members would happen to have the day off were vanishingly small. Employers respected few holidays, but Easter, Thanksgiving and Christmas were sacrosanct.
Now we find ourselves in a era of unemployment and economic stress. Corporations, both to improve their prospects and because workers are vulnerable, have decided that Thanksgiving is an optional holiday, subservient to the gods of profit.
It's a really bad thing. We used to have three days when you could schedule a family party and be confident that everyone was available. Easter has been left behind as Sunday is no longer a day of worship.
Now, the capitalists see Thanksgiving Day as a resource that is left unexploited. The thing is, we are the people for whom this society exists and this is bad for us. We have given over every other day of the year except Christmas to the unfettered pursuit of profit. It is time for us to tell them that enough is enough. For two days each year, they should not be allowed to active their greedy, capitalist motivation.
Which is to say, this tool has run amok. Like a robot that has started disassembling the factory it's supposed to be building, capitalism has gone too far. It seeks to profit from every moment of human life. But, it's a tool. We get to say what the capitalists are allowed to do. We no longer allow them to make the workplace dangerous. We require them to pay taxes and prevent them from dumping their garbage in our water supplies. Every corporation relies on society to enforce contracts, prevent theft, and supply roads to carry goods. In return fo those, we get to set the rules of commerce.
On Thanksgiving, having your job be involved in retail, or anything else, should be subservient to the needs of society. No one should have to work and no one should be enticed to buy. Capitalism has no place on Thanksgiving. Shut it off. Demand that your family be allowed to exist.
