I recently read a passage from a newspaper.
Therefore alcohol should be banned to enable people to have a long and happy life.
Q1) I'm confusing the part of 'people to have a long and happy life.'. Why 'to' is written between 'people' and 'have'? Because I think above sentence is made up of two part. One of them is 'Therefore alcohol should be banned.'. The other is 'Because it enables people have a long and happy life.'. So, I think this sentence have to remove 'to'. Am I wrong?
Q2)The comma is not using between 'Therefore', 'alcohol'. Is it correct?
Thanks in advance.
