'Scabs'? The taxi firms have bent over backward to keep competition out of the market, and now you're saying they should get solidarity because they want to hold consumers hostage to their monopolistic demands? Consumers who already pay more for their cabs than in any other US city?
Uber is not undermining the leverage the strike is creating. The cab companies are still losing money from not operating. It's just that now people who needed cabs to get around aren't as screwed as they would be if no driving services were operating.
