This is really a fairly positive development on balance.
First, fast food restaurants will automate. Machines don’t earn a wage.
Second, family restaurants and those that cater to the middle class will close. What will take their place are unlicensed, untaxed eateries on the low end. Such as food trucks. On the higher end, dinner clubs where you eat in a home and have a really nice fixed menu dinner will become more widespread. Also unlicensed, unregulated, and untaxed.
The same sort of thing will happen in other industries, with the key difference being that any remaining businesses that can move, will move.
So the leftists strangle their own taxation stream, expand undocumented businesses, and cause more businesses to move to places where they’re decently treated. Some businesses will close which is of course sad, but many will reopen in some other form or fashion.
Is that not what Uber has done? Provide a service cheaper with a tech/convenience advantage.
