The thing that bothers me most about your comment is not how wildly inaccurate it is (which is true) but the modding it got which reflects the amount of people that share your ignorance.
First, every single developed country I can think of has some sort of "guaranteed basic income". I can't think of any country in which rampant slouching ensued and society collapsed upon itself. The reason why this didn't happen is in your own comment:
If my housing and food were guaranteed to be paid for, for the rest of my life, I'd never bother doing a damned thing past that. I'd have endless hobbies and diversions and time-wasters, but I'd not get a job.
Sure, some will work hard for really no reason, but many will just choose to exist
What you seem to fail to understand is that the basic income you are guaranteed by the state is just that - basic. It covers housing, heating and most of your basic groceries. It doesn't cover computer equipment, video games, cell phone, books, drugs, clothes, condoms, beers at the pub, toys, sports equipment or coffee.
If you're telling me that you will be content with just the bare basics you will get from the state, you can achieve something fairly similar all by yourself. Work part-time, two shifts a week, in Walmart. Rent an one room apartment. Drink only bulk bought, store-brand soda and eat boiled potatoes and bread. Here it is, your slouchy heaven.
