Uber and friends need to pay a tax which pays back (at least in part) all those who've invested in the current infrastructure based on assurances from Government. I'm not saying they have to get paid back for anything they have done that is speculative, but they need to get paid back something. Is it really that huge a tax to pay? I'm sure they could pay it back over 20 years or something and the government can write bonds against it to pay back taxi drivers immediately.
