A law that requires all service providers to be hired only through a designated state-run portal. People get the right to publicly review anyone they hire. Everyone sees the reviews before hiring a service provider.
People don't always do their research before hiring someone. Likewise, after the service is complete, people don't bother reviewing. Also, there is no ONE place where all the reviews can be found. Through this mandatory portal, everyone gets to see the reviews before enlisting someone's services.
Some services are rarely needed so the providers aren't incentivized to build good relationships with regular customers. This makes the quality less important to the provider.
Such a platform would instill a habit of checking reviews before hiring, decreasing people's chances of being exploited.
Consequently, increase overall quality of service by making bad businesses go extinct.
During the process of enlisting someone's services through the government-run portal, you can check their public reviews/rating.
Reviews are public only if the reviewer is willing to have their identity shown. The reviewer's identity is confirmed via a state-issued authentication certificate. The reviewer can opt to have the review available only to the service provider or only to the government-appointed quality control service. The quality control service is responsible to protect consumer safety, etc.
People can filter reviews by:
This makes providers work harder to provide top quality services in order to remain in business.
By hiring people "off the books" on the black market, nobody sees you complain if things don't work out well.
