It was a compromise to get the slave states to agree. Just like the second amendment and the make up of the Senate.

It is time to redo the constitution. But we can’t do it until we cure the cancer of the Confederacy that has infected the Republiklan Party

To be more proportional to the population, it could help somewhat. The smaller states each get one House seat. Larger ones get multiples of that based upon population. This fix wouldn’t take a constitutional change, just updating a law from long ago that set the House size at 438

If your state's not a swing state, then it will be largely ignored by presidential campaigns. (Which, at least, will spare you the barrage of awful TV ads.)

My faint hope is that technology will enable a broad redistribution of the population, making the Electoral College more reflective of the popular vote. That, in turn, would make it possible to do away with the Electoral College via constitutional amendment.

Thanks

A small state still only gets 1 House seat. But a state with 70 times that population gets 70 seats. This lightens the imbalance but doesn’t fix it since the Senate is still 2 seats per state. We can expand the House since that’s only set by a law. Anything else involves a constitutional change or rewrite which is dangerous if too many Christofascist Republiklans get input

And the senate is just unfixable as you note, without a serious constitutional change, which is not possible these days.
