CMV: The belief that we can survive on an economic system where everyone receives a UBI and does work that they choose for themselves is impractical and unrealistic.

Disclaimer: I call myself a social Democrat, which I interpret to mean that I support a capitalist system with checks and balances and am *not*, strictly speaking, a "socialist". But I am many, many miles away from the typical socialism hater. I'm the kind of bleeding heart that considers the label "social justice warrior" to be a compliment. Just so you're clear on where I stand. (and no, I won't be debating with you on SJWism or anything outside of the scope of what I'm focusing on here) 

I don't know what economic system you want to use as a label for a system where we utilize a Universal Basic Income and free people up to do the kind of work they find meaningful, but that's what I'm referring to here. That seems to be one of the major motivations behind a non-capitalist system, that we can free people from the hell of having to do mundane work by providing them with a regular income and freeing them from their requirement to work some soul-sucking job. We then trust that the work they do with this freedom will be enough to keep society fully functional.

I think this is extremely unlikely on the basis that a lot of mundane work, and I mean a LOT, needs to be done in order for us to function. If you want to eat, you need people to grow food, harvest food, transport the food, build refrigeration units, install refrigeration units, maintain and repair refrigeration units, and if you're old enough, you even need them to take the food from the market and drive it to a person's house. Any of this sound like the best possible use of your free time? Would you really give up your aspirations to be a fantasy novelist / coding guru / wall street bets aficionado in lieu of pulling weeds and driving cars all day? 

And I know what you're likely thinking here: automation! You're thinking that every mundane job will be replaced by automation, that we may already be well on our way towards it, etc. To be perfectly honest, I find this line of thinking to be both lazy and ignorant, especially when you assume that, across the board, every boring job will be done by a robot. You likely don't yet understand how making a machine do a specific task in today's world requires a great deal of engineering and software development work, hundreds of thousands of dollars in upfront investment, and then regular maintenance of the machine by a human, all so that it can perform just ONE task. If you wanted to assemble a module with 2 circuit boards, multiple screws attaching each board, then solder on some sensors, attach a few more structural integrity components, then send it on to the next step, this is a machine that will cost you close to a million dollars just to purchase upfront (I'm a manufacturing engineer and have looked into such things). And this is BASIC ASSEMBLY. The flesh version  of a robot can do this, as well as probably 50 other tasks around the factory, and we only need to pay it 50k a year! Automation isn't anywhere *close* to competing with humans in today's world, and we are likely several decades away (IE lifetimes) from it being a practical solution, if it ever happens.

A lot of mundane work sucks, but a lot of it is extremely necessary just to function in this world, and in a UBI system, hardly anyone will want to do it, which basically dries up not only whatever finances the UBI in the first place but also basically everything else we depend on to live our lives in the modern world.

CMV.

Edit: seems like a common response here is that people will still *work* but likely on a part time basis. Realize that that angle still supports my view. If people get to work part time rather than full time, that's less labor, less GDP, less financing of a UBI program that already seems next to impossible to finance.

Here's the thing, though.  A lot of mundane work doesn't *have* to suck.

Take your typical fast food restaurant job.  The customers are cruel to you, the pay is peanuts, no benefits, you're doing the work of three people and a lack of safety enforcement means burns ans cuts are inevitable.

But if a person isn't dependent on their job to live, they're now in a position to negotiate.  People who like a fast paced work environment can say, "hey, I'd love to work here, but you've gotta make sure it's safe" or "I want to be able to tell a belligerent curmudgeon to buzz off".  Get enough of these people en masse, and work conditions start improving.
