WOTC - Grab and the economy

I asked this question in the Wisdom of the Crowd:

Is Grab good the economy?

Here are the responses: (39 Votes)

36 % - It forces the taxi companies and drivers to improve their service
33 % - It charges a high commission to drivers and force them to accept low fares.
21 % - It offers unfair competition to taxi companies.
10 % - It allows the unemployed to find jobs.
