Money spent on startups isn't charity, you do it in the expectation of (in aggregate) profit -- so it's not rivalrous with charities. People who might support museums earn money on investments that they can then use for charities.
If you believe that you are better at picking winners (slop startups vs non-slop startups) than the rest of the investment world, then that's a valuable skill that you could use to earn a lot of money that you could then use to support museums if you choose.
It's a deeply capitalist perspective to respond to a criticism of the excesses and inefficiency of wild, unfounded capital speculation with 'Well if you so smart, why ain't you rich?!?'
Well, let's go with a learning exercise. Do you think that you should dismiss the fact that someone said something dumb because you perceive them as being on the right side? Then I guess it's good for you.
Well if you are very against capitalism, that would be pretty bad, but ONLY if you are then also a hypocrite working for amounts of money that would make anyone not in the top 20 percent of the world population's eyes pop;
Deduct extra points if you ever accepted stock options, ever tried to start a startup or did a side hustle because you wanted MORE than the bare minimum you need to survive. (Like those capitalist pigs do!)
Or if you are typing this from a mobile phone or laptop computer that costs an amount of money that would be unimaginable to the typical person for most of human history.
Otherwise you're golden. Socialism truly is the superior moral position. It's so obvious we can all agree. And you should lead by example by giving away everything that you might need less than some other random poor person out there.
Is that so unreasonable? Lots of people post that Wall Street corporations are dominated by short term, next quarter thinking. If that were true, then shorting those stocks would be a profitable plan. It seems reasonable to point out that if one is so sure corporations were going to tank because of short term thinking, they could get rich by shorting the stock.
Looking at a chart of the S&P 500 over decades, it's hard to see how anyone could make money by betting on corporations only being interested in short term results.
The S&P 500 is a list. 80+% of the companies on that list when it started are no longer on it.
Betting on business in general over long time periods tends to be a winning proposition. Betting on an individual company tends to be less of a winner in general.
I agree completely. Museums, culture, and other wasteful/pointless excesses should be deducted from profits - at the discretion of the profiteer - only after the actually useful work of poisoning the drinking water to generate pornography is complete.
Nobody is going to make money on museums. As such, you either provide for them through tax dollars or you convince people to donate.
