Politicians are motivated by power, not by your needs. We have had repeated examples of just how bad states truly are at providing for people's basic needs. Every time it's been tried, it's resulted in chronic shortages, often to the point of starvation. The USSR, Cuba, North Korea, China (before they went capitalist). I'm going to take a wager and say that the days when the USSR was still a major world power were before your time, and if I'm right, I strongly encourage you to do some reading on what it was like for the people who lived in it.
