Not dangerous, just corrupt and wildly idealistic. The EFF manifesto makes for a wild read with all the crazy promises and policies proposed, many of which have very little to do with Marxism. Nationalisation might be one of their few good proposed policies along with land reform.

Already the first few pages of the document listing their accomplishments are full of contradictions and exaggerations:

The EFF got former President Mr Jacob Zuma to pay back money spent on non-security-related upgrades at his homestead in Nkandla.

Is that why the EFF tried to court Zuma and get him to join the EFF as a partymember?

The EFF held a successful national shutdown on the 20th of March 2023 to demand a stable supply of electricity and the resignation of Cyril Ramaphosa.

Lmao! I don't think I saw a single EFF member engaged in this "shutdown" outside of the city centres of South Africa's capitals.

The EFF has gained credibility at institutions of higher learning by constantly winning SRC elections. The EFF has built the confidence of black people and confronted racism everywhere where it encounters it.

Ok this is at least true and one of the things that the EFF is good at. Very good at making racists scared.

Onto addressing unemployment:

The EFF will establish State-Owned Housing and Roads Companies that will deal with the social housing and roads infrastructure backlog. In the short to medium term, this will result in nearly 4 million jobs.

A good idea, but idealistic as I fail to see how this will generate four million jobs in five years. The construction industry in South Africa only employs 1.2 million people currently.

The EFF will establish a state-owned security company that will insource all security personnel working in government facilities. This will immediately create 1.2 million sustainable and quality jobs without departing from the existing government budget expenditure.

1.2 million people working for a security company to protect government property? How is that going to ever happen? I guess they plan to hire some of the 2.7 million registered security guards, of which only 600 000 are currently active/employed. I still don't see how this is even possible. To create a security company with double the amount of employees as the entire security sector within 5 years. Just because someone is registered to do a job, it doesn't mean that they will do it.

The EFF government will hire all military reservists permanently.

The EFF government shall mandate that each person undergo compulsory military training for a year or six months after matriculation, offering life skills and discipline.

Bringing back mlitary conscription? For what? I don't see South Africa facing any current threat that requires that. Or hiring all reservists.
