Quote from Ghost of Cutten:
The startup costs of a silicon fabrication factory are enormous. The startup costs of a trader are miniscule. They are not comparable.
The problem for the retail trader is overhead, not startup costs. After tax, commissions, and living expenses, can you grow capital reliably? This is not easy unless you are already borderline rich. For example, 20% per annum with occasional 20% drawdowns is an excellent return, yet after taxes you are talking 11-14% in most civilised countries. So if your living expenses are 100k a year (a comfortable middle class overhead) you need 700k+ in capital to generate that.
Now, one 20% down year and you have 560k. It has just become hard to meet your overhead.
The ways to avoid that are i) higher returns per unit risk (requires extreme talent and hard work) ii) expat to a tax haven to boost your returns by 1/2-2/3 (requires abandoning friends and family, and usually living a soulless existence in a boring place) iii) start a fund and try to enter the big leagues (lots of bureaucracy) iv) find a way to generate good income, rather than return on capital (can be done but usually these edges disappear after a while)
Pick your poison.
