If it is on the employer to make a value judgement on your skills, then isn't it also up to the window shopper to make a value judgement on the merchandise?
Well, yes - but in my original comment I didn't say that if you get half a feature behind your competitor, you should trash your merchandise and go do something else. I complained about people willingly making and selling shit, covering the deficiencies up with marketing.
In hiring analogy, it would be as if I couldn't code at all, but could talk my way through the interviews - and so instead of actually learning to code, I'd earn money by getting employed at companies and trying to extract as many paychecks and benefits as I can and then quitting before they figure out I'm a fraud.
Me investing my time to get a job through pure charisma, without bringing any merit to the table, is like selling products on pure marketing. Pretty dishonest, and also poisons the ecosystem for everyone.
That said, most of my peers who are objectively better than me are already employed, and it's up to employers to select from the available pool of employees. My responsibility is to truthfully present my skills during interview.
