> and expecting a good wage

Wait, you added that part just now.

I don't see why you couldn't drive a taxi for a living (though I don't know if that is all that was meant by "career"), but taking for granted that you will be paid well seems off.

Low barrier to entry.

Only middle class professionals have "a career" and therefore deserve to have enough money to live on, don't you know.

It's the primary reason we don't need a minimum wage - working in the service industry or any other relatively unskilled work isn't "a career" so it doesn't matter if it only pays 2 bucks an hour, so goes the reasoning because nobody should be expecting to do it for long or make a life out of it.

It's myopic.

If teachers can’t be expected to support their family off their income, why should someone doing something that can be crowd sourced as a side gig? Just because I can make $15 tying peoples shoes doesn’t mean that I’m entitled to support a family off of it.

Because it is in your(society) interest that people can support themselves and their families with just one job. Otherwise you end up spending more on benefits and support not to mention on all the problems that come with chronic unemployment.

>> If teachers can’t be expected to support their family off their income,

Why the f*ck should teachers not be paid enough to support themselves and have a life? Wow.

> No, I'm still confused. What is the problem with being a taxi driver for life and expecting a good wage?

No, I'm still confused. What is the problem with being an elevator operator for life and expecting a good wage?
