If you're not supporting yourself or others on a wage, then no, you don't need the minimum wage. However other people are doing that, and do so and it's not fair to say "well, you shouldn't have this job because that's not what this job is intended for."
You think a single parent would be working a minimum wage job if they had an easy opportunity to do better?
Besides, by just saying "create more jobs." You're getting to an issue we're just now starting to have a taste of. There simply isn't enough work out there for everyone and it's going to get worse. Any attempt to stop that from happening is just standing in the way of progress and making people work for work's sake.
We are at a point now where you could provide low quality, but edible and nutritious food in a fast food style, with minimal human interaction and none required actually touching the food at any point from farm to plate.
It's not quite widespread yet, but you know that companies are going to pick up on it soon and you'll within a couple of decades you'll find "hand made" food a luxury even among drive through burger chains. If you want that burger that's slightly off the bun with the ketchup all on one side and the cheese stuck more to the paper than the bread, you'll have to pay for that luxury.
The fact is the amount of work require to run society is decreasing faster and faster. Self driving cars and trucks are in the testing phases. Warehouses are already becoming computerized. The whole logistics sector is on the verge of a job crash. And while some of these jobs are simply being shuffled (someone has to make and program the robots doing the jobs.) many of them are simply disappearing. And that's just one (albeit very large) sector of the economy.
Rather than fight that for the "right" for everyone to have employment, why don't we just admit that society doesn't really need us all anymore?
