It's actually more of a legal question. Uber only manages to work through lots of questionable tactics of which many are illegal: - Most of the uber drivers don't actually pay taxes - Most of the uber drivers only work for uber which makes the self-employment fictitious. This allows to disregard things like minimum wage and payments for social security. - Most of uber drivers don't have a permission for transporting people. This puts customers at risk. - Most of uber drivers don't have an insurance that covers transporting people commercially. All these apply even in the case where private taxi companies are allowed. Uber's business model is based on exploiting the drivers, disregarding safety regulations and dodging taxes.
