Do you agree? Due to huge and very motivational advertisements humans spend more than what they actually need.

It all depends on the psyche of the consumer. You have different types of consumers, and each responds differently to advertising and marketing. The emotional consumer purchases items based on how they're feeling. Let's say that a man sees a marketing campaign for the new GMC Armada SUV. The campaign features a family going on long road trips together, enjoying picnics in the park, and having fun at the beach. This man is a family man himself, with a wife and 3 children. He is now emotionally attracted to the marketing campaign and feels that he needs to purchase that specific vehicle in order to make his family happy. He now wants what has been marketed to him, so he goes out to buy said vehicle. He is the emotional consumer.

The next type of consumer you have is the one who buys just because the marketing is attractive; that is the impulsive consumer. They buy just because the colors are nice, the packaging is appealing, and the idea of having the product is attractive to them. They feel that perhaps one day they will have a use for the product. There is no real reason as to why they buy it. Even if the price isn't right, they'll still purchase it.

The third type of consumer is the practical consumer. They monitor what they buy and why they buy it. They are loyal to certain brands and products and will not buy anything if it is not that particular brand. They like what they buy, they like the pricing, and aren't really motivated by the marketing. It is more about the quality of the product and the company's ability to create the products that fulfill the needs of the consumers.

In so many words, marketing is made for every type of consumer. Do I believe the people overspend? Not in general. Mostly, you have overspending in areas like women's care products like makeup. That is a billion dollar a year industry where women will spend - on average - USD $350 in one shopping trip to the local MAC or Sephora store.

I agree with M's Shaikha answers, thanks for the invitation. ..

I dont think that emotion leads to a purchase that is more then a need of the consumer.Yeah targeting someone's emotions can work as a stimuli but cant motivate someone at that level.

Thanks

I agree with the answer given by colleague Sheikha Ali

agree with Shaikha Ali Al-Sowaidi 

Agreed, it is true in several aspects.

Thanks for your invitation, I agree the same.

It is a natural human instict to want more/beter. If it werent for this inclination we would not have evolved/developed to our current state. Wanting more is a good thing its a motivator of sorts but, only if the behaviour is practiced in a responsible/sustainable manner.

My answer is "yes". Motivational and consistent advertisement leads to spend more than one actually neede.

It has a big impact on person choosing certain products and services. But if the budget is tight, I think people tend to spend wisely. 

Yes. Many a times these advertisements create a need in the human minds for a prodcut or a service which they actually don't need. Fulfillment of these virtual needs leads to excess needs by humans.
