UBI is implemented tomorrow. Every citizen gets $1000 per month.
Landlord now knows you have an extra $1000 that you never had before. Why wouldn’t the landlord raise prices?
Now you have an extra $1000 a month and instead of eating rice and beans for a few meals you go out to a restaurant. The restaurant owners know everyone is eating out more so why not raise prices and maximize shareholder profit as always. The restaurant/corporation is on TV saying, “well, demand increased and it is a simple Economic principle that prices had to increase. There’s nothing we can do about it”.
Your state/country has toll roads. The state needs money for its deficit. UBI is implemented and the state/country sees it as the perfect time to incrementally raise toll prices.
Next thing you know UBI is effectively gone because everything costs more and billionaires keep hitting higher and higher all time net worth records.
Real estate isn’t that simple. Way too many layers of work and bureaucracy between wanting to build something and making it happen even when you have the cash to make it so. Many of these layers are essential, others like nimby idiots are not. We need more housing for people and it would take a huge increase in available housing to have any negligible effect on any one individuals house/property value.
As for restaurants. It’s also not that simple. Most restaurants fail in the first year or two. You have to figure out what type of food is in demand and then maybe be willing and able to shift to something else if the market gets oversaturated.
