Of course, that is the point and it is very well summarised. From a mathematical point of view it is not worth playing the lottery, but for the mere possibility and the small cost it is worth it.
Although from a mathematical point of view it is worth it in cases where there is a jackpot so that the mathematical expectancy is positive, but this would be a topic for another thread.
The 'tax' I already pay from time to time, I already pay it because from time to time,
I would say once every 2 or 3 months, I buy lottery tickets.
That is exactly how often I play too! I think that this is because we share the same culture, being as we are both from Spain, and we are from the same demographic segment (male/middle class/similar age).
In fact, here we have the habit of playing Christmas lottery, which costs 20€ a ticket (probability is still small but not as much as in the lotteries mentioned in the OP), and it is a long time that I prefer to save this money and spend it throughout the year, so I maintain the hope for a much longer period.
A classic millionaire lottery ticket is what it is, a dream that can come true, people in my geographical area say: dreaming is free, well with the lottery nope, but it has the category of impossible dream, but this dilemma is so cheap, the dreaming, that is makes it so appetizing. ($1, e.g.)
Someone on the Internet (influencer) spent a million dollars, that is, a million tickets and was able to recover $750,000 or a similar figure, that simple didactic example tells you that without doing much math, you only need one ticket to win the prize fat.
If someone actually spent over 1 million of dollars on lottery tickets and only managed to recover a fraction of that the initial investment was, it tells you much on the dreaming and possibilities someone with some bucks can have to get the jackpot.
That is the main reason I do not play lottery, in the long run there are other things I can do with the accumulated money I could have spent on tickets, in that sense, we can argue it is slightly similar to gambling.
Anyways, each one of us is supposed to be responsible with their money.
Well, it seems that he was already rich if he was able to spend a million, so I will not judge him, but for the common mortals it makes no logical sense to up the ante. Look:
1€ in euromillions = 0.0000007%
2€ in euromillions = 0.0000014%
So you're paying 100% more to obtain practically nothing in terms of probability. Once you paid 1€ in exchange of the possibility it should be more than enough, and those who seek to play with probability instead should look for a different game and forget about getting rich in a stroke of luck.
