Answer:
Yes, I think people have the right to sleep in a park because the park is a public place.
Solution:
My first solution would be that jobs have better pay. Most jobs do not pay enough money to keep up with the cost of living. Pay should actually be $30 an hour to keep up, but on average it's $8.00 -$15.00 per hour. As brutal as it may sound, jobs do not need to raise their paying hours because they can hire millions of people who won't complain about the pay, and if they do up the pay, then that'll mean less money for them.
Try to learn a skill. Since learning a skill takes time and a lot of discipline, most people don't want to do it because they figure it may be too hard or too difficult, so that's why they decide to just work in physical, hard labor work for the low pay.
