Playing the lottery is a terrible financial idea

Buying a lottery ticket is one of the most irrational things a person can do with their money. Although it's sold as "a dream for a few euros," mathematical, economic, and psychological realities show that it's a voluntary tax on people who don't understand probability.

First, the odds are brutally unfavorable to the point of absurdity. In the Spanish Primitiva lottery (6 numbers out of 49), the probability of matching all 6 is 1 in 13,983,816. In Euromillions, it's even worse: 1 in 139,838,160. To give you an idea, you're much more likely to be struck by lightning (1 in 500,000 in your lifetime) or to be in a plane crash than to win the jackpot. The lottery isn't a game; it's a draw designed so that almost no one ever wins the grand prize.

Second, the expected value is negative and brutal. For every euro you gamble, you recover on average between 40 and 50 cents in the long run (depending on the game). That is, for every €100 you spend over the years, you mathematically lose between €50 and €60. No casino in the world offers such bad odds; not even the most predatory slot machines reach that level of exploitation.

Third, it generates a toxic psychological effect. The lottery exploits the cognitive bias called "availability": because we see winners on TV, we believe that "it could happen to us." But we don't see the millions of weekly losers. Furthermore, it fosters a "magic bullet" mentality instead of sustained effort. Studies (such as those in the Journal of Gambling Studies) show that regular lottery players tend to belong to lower socioeconomic strata and allocate a larger percentage of their income to this "regressive tax."

Fourth, the money you spend on the lottery could generate real wealth if invested. €10 a week for 40 years at a 7% annual compound interest rate (the average historical return of a global index fund) grows to over €100,000. The same amount spent on the lottery becomes… nothing.

In short: the lottery isn't cheap entertainment; it's a trap designed to extract money from those who can least afford it, disguised as hope. If you want thrills, go to the movies. If you want to get rich, save and invest. The only guaranteed way to "win" the lottery is to never play it.
