Bills are revised in select committees (amongst other places). They are finally approved once revised.
Crumbs, not that it really matters as all this select committee nonsense we're talking about came about because another poster said contracts had been ruled unintelligible by a select committee.. But since you're keeping on about this, no, you're mistaken yet again, bills are not revised they are investigated or further evidence is gathered by the SC, after which amendments are returned to the House to a full House committee... Again, this is not the revision of law!
I'm mystified by your comment that the jobs didn't exist before Uber. I was using minicabs decades ago.
Were you using Uber drivers decades ago? No. So Uber work didn't exist decades ago did it then? So I stand by what I said - that the Uber work didn't exist before Uber. 
Do you honestly not understand the social and economic implications of deregulating low paid employment in this way?
Oh, you mean do I not agree with your skewed viewpoint? Do you honestly not understand the freedom of opportunity, the flexibility, the incredible enrichment that can have people doing multiple careers and earning money at the same time with companies like Uber in the gig economy? Do you honestly not understand it's 2017 and not 1848?
Most workers in this category have little or none of the vaunted flexibility - the flex is all on the employer's side.
Seriously, what part of "you can work whenever you want, at whatever times you want, and for whoever you want" do you not understand about driving for Uber? Kindly answer that.
