Let's be grateful there aren't any cynics in this forum.
We should seek to make sense of microeconomics no differently to how Attenborough seeks to understand the natural world. To observe, analyse, explain, and ultimately try to understand what's going on. We can't infer he has a "hatred" of dung beetles because he explains their activities!
Price floors introduce distortions which reduce efficiency. It's easy to look at one tiny labour market, like NSW Amazon delivery drivers, and think it's great drivers will make more. Now consider when they go to spend that money. They will have slightly reduced range (some sellers will no longer be profitable and will cease selling), and their pay won't go as far, since they themselves will, like everyone else, be paying more for delivery.
Now for the mind blowing part: consider what happens when everyone attempts the same trick of legislating a price floor in the market for their own labour.
Now everyone's pay goes up 20% but when they go to spend it, it only goes 60% or 50% as far as it once did when markets were efficient.
This doesn't even touch on 2 other major considerations of price floors:
1. If wages are low in one profession, you must ask "compared to what?", and if the answer is another higher-paying profession, then you should consider switching. That is allocative efficiency. It's easy to overlook the gains when thinking of a few hundred workers, but across an entire populace, the gains are enormous.
2. A price floor on labour will put some people entirely out of work, since some people's marginal value will be less than the floor. As a rule of thumb, any NSW driver who doesn't produce A$37.80 of value per hour for Amazon won't have a job after the measure is fully phased in.
