I have really been trying not to engage, but @CreteBound actually the biggest issue being faced at the moment in the low wage space you're talking about (for Dubai at least) is not the point you're talking about. That space isn't perfect by any means but there's a lot of attention to the issue and new laws being introduced to force employers to provide appropriate accommodation etc.
The developing issue is in a very different. Over the last year or so there has been a mass influx of white collar workers, largely from the sub-continent either on tourist visas or take advantage of some of the long term visa options now available at relatively low cost. These people struggle to find employment without connections and without income, and having spent a large amount of money on coming to Dubai and said long term visa options, get very desperate. Employers take advantage and as a result salaries are being pushed very very low.
These jobs don't come with accommodation, and whilst no one is locked up in labor camps in the desert in these roles (which is pretty unusual now anyway because employers doing this would be in serious trouble if caught), they have zero safety net and because of high accommodation costs end up having to rent illegal (and unsafe) partitioned accommodation which the government is now clamping down on. These are salaries that you simply cannot live on and very often are actually lower than the salaries that the people you are focused on are earning, particularly when you take into account the fact that blue collar jobs usually come with accommodation and food provided.
We're talking people in HR/marketing/IT with university degrees accepting jobs paying the GBP 400 a month, being expected to work 12 hours a day, 6 days a week, putting up with horrific bosses because they are terrified they'll end up without a job at all and there's this idea that if you get your first job you get UAE experience and then can move upwards from there (I'm not clear this is actually true for 99% of people). I saw an example recently of an employer interviewing a strong candidate for a marketing job who didn't have UAE experience. Budget for the job was around GBP 4,000 a month and the employer was willing to pay this much for the candidate (they were down to last 3, the candidate had strong experience from India and the lack of UAE experience wasn't a dealbreaker). The candidate completely off their own back brought up salary and said they were willing to work for GBP 400 because they needed the job. Good employers will ignore that, but let's be honest most will take advantage.
Cost of living in Dubai is roughly the same as London FYI, and there's no (real) safety net if you find yourself without a job.
I don't know what the solution is. A minimum wage doesn't work as these new visa types make it easy for people to technically be employed as contractors and therefore fall under the radar for any controls. That's even worse because then there's not a requirement to provide medical insurance. I suppose it's that you stop people coming unless they have a job in advance, but actually managing that in practice is close to impossible and no matter how many times you tell people it's a bad idea people still try because there's always a friend of a friend who it worked for.
Same thing happens with British people in their early 20s, but they're usually far less qualified, and they come up with the dream of making millions in real estate.
