Liberals very much have theories about why things happen. Marxism in a way grew out of liberalism. Marxism is just a better (meaning: more predictive) theory about society, not necessarily the first one to exist.
The problem is that liberalism is highly beneficial to capitalists so they spend a whole lot of money fabricating evidence and manufacturing consensus that liberal theories are “more correct” than e.g. marxist theories. When that doesn’t work out they either coup or bomb their opponents.
The academic apogee of this is the famous “end of history” bullshit, claiming that liberalism is the correct model of society and no better theory can be formulated at all (which literally never happens in science).
As this is becoming more and more obviously wrong (due to the heightening contradictions inherent to liberalism), liberals are sure to either abandon the scientific approach altogether (become right-wing chuds) or embrace the better, more predictive theories about society (become marxists or adjacent).
