Technology doesn't bring disconnect. I'd argue liberalism does, and individualism.

Liberlism glorifies individualism: it is the individual who shall be responsible for itself, for its successes and failures. This makes people center on themselves.

But humans are social creatures, so when society tells you that can only rely on yourself, you simply ignore society and focus on your relatives, your family, and maybe your extended social group, which is far, far smaller than the whole society.

Liberalism is basically a doctrine that tells people that the state will abandon them and they shouldn't rely on it. People will mechanically fall back on a fascist regime that tells them that they will be taken care of and granted the privileges they deserve.

Ergo, liberalism builds fascism.

Another way I see this is that fascism is the fail state of societies. A society always fall back to some sort of fascism. And there liberalism comes to tell you that the state, the organisation that structure the society, should disappear or do nothing.

The solution is dirty easy: the government needs to be a government and do something for the people. Fund the schools, the hospitals, public transports. Take the money where it is. Forbid the financiarisation of the housing market, so house can house people instead of being another kind of gold. Ensure people have enough money to eat and shelter. And there you go. People don't need fascism when they're being taken care of.

But the only things liberals do is pretending that there is no money for this shit. Of course, they're hard at work so the state can get the least money possible.
