Why do we keep offering deference to the Royal family in the 21st Century.

For me the Royal family represents inequality and conservatism, a dynasty that has no place in the modern world. Just look at the above photo, it represents everything that's wrong with the monarchy. The sense of entitlement on one side. the unquestioning deference on the other.
Far from uniting the country, the monarchy's role is seen by many people to be illegitimate and offensive, and simply entrenches hereditary pivilege at the heart of public life. While our government patronisisingly preaches democracy to the rest of the world, they still preside over an undemocratic system at home with an unelected head of state .
With their vestiges of privilege, the royal family continues  to  award themselves medals, appoint themselves to top military ranks that they simply they do not deserve. Allow themselves to be nominated as patrons of charities , degrading the real efforts of those who have really made general contributions. At a time when Britain  is going through a time of national economic and social stress due to Brexit , austerity, incoming roll out of Universal Credit and so on. The Conservative Government currently imposing a draconian, financially crippling sanction on jobseekers because they dont want to pay out any money to those who are unfortunately out of work, while the Royals get there houses refurbished  at tax payers espense, while many people cannot afford to heat their homes or put enough nutritional meals on their tables.
While so many far more importanst issues face us everyday, this continuing fawning to members of the Royal family and their hangers on,I simply find embarrassing. At a time of inequality, when public services, public sector jobs, wages, attacks on the most vulnerable among us continues, in the  most savage round of austerity meaures ever seen in modern times,  how the hell can some people still be proud of this patronage ridden monarchy is beyond my imagination. It certainly reinforces my feelings that some people are born better than others. It's the piacle of the class system which has held or socirty back for so long, enforcing the idea of an elite rling class.
Their nauseating displays of riches, power and privilege ,is simply an affront to human decency.I believe in a society, where we can all look into one another's eyes as equals , whatever our purpose or position in life. This continuing deference to them is simply offensive, and it has its consequnces. Since  you and I, and every taxpayer across the land will have to fork out tens, if not hundreds of thosands  of pounds for the Queens son's forthcoming marriage. The Royals  have claimed that they will be paying, but the truth is, that on May 19 it is the taxpayer who who will be lanfed the enormous bill. I don't believe thiw is ok, they need to pick up the bill. So on this note would urge you to join more than ten thosand people in signing the following petition calling on MPs to make sure the royals pay for their own wedding.https://www.republic.org.uk/petition/royal-wedding
Here's to a better, more egalitarian world, yes a brighter monarchy, confine these pointless ornaments to the dustbins of history
