Because capitalists made it so that competing with them is extremely risky.

Money barrier/immediate life threat/limited market.

Economies to scale is a hell of a thing

Pretending this is a good faith argument.

Because the market is already saturated, capitalism is not the freedom of business, it is the freedom for business.

Because they're mostly wrong about their premises and thus conclusions. It makes perfect sense that they keep being poor until they fix those.
