Well, yes of course they are: a much higher proportion of the population have degrees these days. In any case, don't we want them to have a good education?
But, more importantly, surely most MPs are working class in the sense of having to work for a living and not living on rents, interest, profits etc?
We already have plenty of MPs who are objectively from working-class backgrounds. The problem is that most of them (with honourable exceptions like Dennis Skinner) don't engage in politics as representatives of their class.
They don't struggle on behalf of the exploited majority of the population against the ruling class, the owners and managers of capital.
It doesn't really matter what kind of work they used to do, or how many degrees they have. What matters is whether they are prepared to fight for working people as a class, and how classy they are at that kind of work!
