most parent are both working to earn money for the family. Feeling guilty about never being there with their kid and to make up for that they spent money buying whatever their child wants and never asking for anything in return. This causes their kids to get more spoiled and relying on parents. Some gets too pampered that they can't stick to their job when things get tough.
In my opinion, I think that parent should not spoil their child with what they want as to make up for not spending time with them. Such parent will only spoiling their child and may result that their child will ask for more in the future.
