Just curious to see people's take on this scenario. Imagine tomorrow the government announced that every single adult and child would be provided with the most basic level of necessities as follows:

Food
staple foods such rice, beans, vegetables, water, etc such that each person would receive just enough to consume three nutritous balanced meals each day.

Shelter
An apartment with approximately 500 sq ft/person or couple + 250sq ft per child or equivalent there of. A basic level of electricity, gas, and water would be covered.

Healthcare
All healthcare would be paid for but only doctors get to determine which procedures/tests are necessary.

No other laws would change. In this scenario, what would the country look like in 5 years? how about 10 or 50 years? If you consider this unsustainable, how long could it last and why? Would general happiness increase or decrease?
