my 2 cents woth..here goes, people do things they shouldnt on shabbos including texting and using technology coz they have little (notice i use little and not non because EVERY yid has a spark that needs to be ingnited) relationship with G-d.
it maybe because they never learned how to have a relationship with human coz if u dont know how to have a relationship with people you dont know how to have a relationship with Hashem, how u supposed to learn? if you are numb to your parents/teachers coz you never had a good relationship with them, you will be numb to Hashem.
