3．The sharing economy，represented by companies like Airbnb or Uber，is the latest fashion craze．Rut many supporters have overlooked the reality that this new business model is largely based on escaping regulations and breaking the law．
Airbnb is an internet-based service that allows people to rent out spare rooms to strangers for short stays．Uber is an internet taxi service that allows thousands of people to answer ride requests with their own cars．There are hundreds of other such services．
The good thing about the sharing economy is that it promotes the use of underused resources．Millions of people have houses or apartments with empty rooms，and Airbnb allows them to profit from these rooms while allowing guests a place to stay at prices that are often far less than those charged by hotels．Uber offers prices that are competitive with standard taxi prices and their drivers are often much quicker and more trustworthy．
But the downside of the sharing economy has gotten much less attention．Most cities and states both tax and regulate hotels，and the tourists who stayin hotels are usually an important source of tax income．But many of Airhnb's customers are not paying the taxes required under the law．
Airbnb can also raise issues of safety for its customers and trouble for hosts'neighbors．Hotels are regularly inspected to ensure that they are not fire traps and that they don't form other risks for visitors．Airbnb hosts face no such inspections．
Since Airbnb is allowing people to escape taxes and regulations，the company is simply promoting thefts．Others in the economy will lose by bearing an additional tax burden or being forcced to live next to an apartment unit with a never-ending series of noisy visitos．
The same story may apply with Uber．Uber is currently in disputes over whether its cars meet the safety and insurance requirements imposed on standard taxis．Also，if Uber and related services flood the market，they could harm all taxi drivers'ability to earn a minimum wage．
This downside of the sharing needs to be taken seriously，but that doesn't mean the current tax and regulatory structure is perfect．
